Control the load with the TV remote control. Remote control of light

If you take the remote control in your hand and wave, then usually a pointer appears on the TV, which you can control the movements. But what if the pointer does not appear, how not to shake this remote?

The remote control can fail to work for a huge number of reasons, and not necessarily it should have broken or failed. The more complex the technique, the greater the chance that something can fail. It is worth noting that one of the main causes of the problem may be ignorance of the instructions for the TV. Tell me honestly, did you read it before using it? At least the main points? Probably not, but trust me - there are answers to almost 90% of your problems.

Let's take a look at a quick guide to using the remote, maybe it will give you the right ideas (the remote in the pictures is an old one, but nevertheless, its principle of operation has not changed since then):

Possible reasons

If the instructions above did not help, let's look at the main scenarios, having analyzed them, it will be possible to understand what happened to the Magic Remote.

Do a simple test before you start: Point the remote at a digital camera (like the one on your phone) and press any key. If at the same time you see a flashing light in the camera display, the remote control is working (and the problem is most likely in the TV), if you don’t see anything, there is a problem with the remote control.

1. Batteries are dead on the remote control- when you press the remote control buttons in its upper front part, the red indicator should light up. If this does not happen, the batteries may be dead (or not at all). Check (preferably in another device or using the indicator on the batteries themselves) and replace them if necessary.

Selectively check the functions of the remote control - if nothing works at all, the batteries are most likely dead.
Make sure the batteries are working.
The polarity of the installed batteries must be observed according to the indications on the remote control.

2. The remote control has lost connection with the TV (or has not yet been connected). This is one of the most common cases. The Magic Remote works via Bluetooth and in order to control the TV with it, you need to "acquaint" them.

But even if you have already done this, the TV may forget your remote. This can happen due to a crash or if you hold down the button combination for a while BACK+HOME- after a few seconds, the functions of the magic wand will stop working and only the ability to use it as a regular remote control will remain (buttons only). Naturally, pressing these buttons could happen by accident without your knowledge (for example, someone sat on the remote control with a fifth point or the children indulged).

To connect the Magic Remote back to the LG TV, you need to hold down the central button (the wheel, it's also the OK button). If you did everything correctly, after a moment the following message will appear on the TV display:

Registering a New Magic Remote Control...

And after a few seconds, if the connection is successful, you will see the following message:

Registration successfully completed.

If something is still not clear, watch the video, which contains instructions for connecting the remote control:

Make sure that there are no devices in the vicinity of the TV or remote control (even in neighboring rooms) that can cause interference (electronic devices, bright lights, etc.).

3. The remote was filled with liquid- this also happens. No need to panic, remotes, keyboards, phones, tablets and other devices very often shower with water, tea or other drinks.

If you immediately noticed that the remote control was flooded, you need to quickly pull out the batteries, wipe and dry it. If it has been under the influence of liquid for a long time or something viscous has been spilled that cannot simply be dried (beer, compote, etc.), then it will have to be disassembled. If you can handle it yourself, you need to get to the microcircuits and thoroughly clean and dry everything.

4. Batteries leak- not a very pleasant moment, not a single device is immune from this. If this happens, then when you open the battery compartment you will see a white coating. In this case, even if you change the batteries to new ones, the remote control most likely will not work. As in the previous paragraph, it will have to be disassembled and cleaned. By the way, I recommend using hydrogen peroxide for cleaning.(you just can’t buy alcohol anymore, but vodka and other strong drinks leave a residue).

It is also worth considering that if the batteries leaked, then the option of a complete failure of the remote control is possible.

5. The remote stopped working after a year and a half and no matter what you do, nothing helps. This is a known issue that many customers have experienced. There is an opinion that in the early versions of the remote control (2012, early 2013) there was a factory defect.

To solve this problem, you will have to disassemble the remote control and solder it. More about this is written. If you yourself do not understand soldering, it is advisable to take the remote control to the workshop, providing them with instructions at the specified link.

6. The remote control slows down. In addition to a completely inoperative remote control, there is still a problem when it does not work adequately - the pointer moves in jerks, repeats your movements very slowly or indistinctly:

it can be like a short-term glitch, which is treated like this - leave the remote control alone for a few seconds so that the pointer disappears from the screen, then move the remote control again;
if it doesn’t help, then you need to re-register the remote control in the TV (point 2 of this manual);
change the batteries if none of the two options above worked.

Remote control alternative

If you have a tablet or smartphone based on iOS or Android, then you can download a free application for Sart TV LG called LG TV REMOTE. With this program, you can easily control TV using your phone for example.

The remote control (RC) is an incredibly convenient thing, and it is not clear how we lived before without them? With its appearance, we have one problem less, although sometimes another, no less important problem arises - how to set up the remote control?

How to set up the remote?

The ideal option, of course, would be if the remote control is set up for you by a service master. But if this is not possible, then you can try to do it yourself. Let's try to help you with this.

Setting up a universal TV remote

To set up a universal remote for, do the following:

First you need to turn on the TV, because the setting occurs when the TV is on.
Press the SET button on the remote control and hold it until the LED next to it starts blinking.
We take the code table (in the instructions) and drive in a three-digit code that matches the brand of your TV. For each brand of codes, there can be ten or more. When the code is entered, the LED blinks, and after you have already entered it, it continues to simply burn, but evenly, without blinking.
Then you need to check the operation of the remote control, only without using the number buttons. Those. try turning the volume up or down, changing the channel. If the remote does not work, then enter the next combination, and so on until your remote starts switching channels or adjusting the volume.
After the code is selected, press the SET button again - this will save the operating mode.

Your remote is configured, the LED is no longer on, but only lights up when you press any button on the remote. Now you can easily turn the TV on and off, turn the volume up and down, change channels, and select the video source. In a few words - you can use all the buttons.

Now it is difficult to imagine our life without electronic home devices. We use them all the time: both for entertainment and for solving everyday issues. Often these devices are equipped with a remote control function using remote controls. Every year the number of electronic equipment in our homes is increasing, and with it the number of remotes for them, too. But very often remotes are lost, and they have to be searched for a long time.

You can solve this problem by purchasing a universal rolsen remote control, which is suitable for various equipment that has an infrared receiver.

Setting instructions

A remote control is a small device with a keyboard, circuits and an LED, equipped with an infrared transmitter that controls other devices using radiation. The transmission of commands between the remote control and the equipment occurs by entering a special “code” available for any equipment (it is indicated in the operating instructions for this device).

The universal remote control works in the same way, only its feature is that it can memorize several devices with different codes. But for some devices, in particular for rolsen TVs, the code for the remote control is sometimes missing in the instructions. And then setting up a universal remote becomes problematic. But there is some algorithm of actions that allows you to configure the remote control without a code.

It happens like this:

You need to turn on the TV for a channel to work on it.
We dial the combination of the SET and TV keys on the remote control and simultaneously hold them down for a few seconds until the power indicator starts flashing.
We direct the remote control at the controlled device and quickly press any key except SET. If we didn’t manage to do this, then we repeat everything again.

This is how you can set up any universal remote control for equipment without a code. The use of such remotes is very convenient, since with the help of one small device you can control several devices.

To date, any modern technology, in particular, air conditioners, media players, tuners or TVs, are controlled by remote control. Without a remote control, normal equipment control is impossible, since such devices greatly simplify the life of an ordinary person. But since such devices, especially modern ones, have extensive functionality, not every consumer knows how they can be configured. Sometimes, having bought a new TV, a person has to spend hours setting up the remote control by pressing all kinds of buttons, that is, in fact, working by the “poke method”.

In some cases, this leads to negative consequences. The configuration of equipment, for example, a TV set, can be set in such a way that later it will bring significant inconvenience to the owner. To prevent this from happening, you must immediately correctly configure the remote control for the TV. We will talk about this further.

Recommendations for setting up generic devices are given below. Some nuances may differ, it all depends on the specific brand of equipment and its specifics, however, in general, the setup procedure is identical for many remotes. By the way, a huge selection of remote controls for Bravis TVs at reasonable prices is presented at http://pulti.ua/Bravis. So, what is the setting:

First of all, you need to turn on the equipment - the configuration is performed only on the switched on TV.
Now on the remote control itself you need to find a button that activates the setup mode, it can be Setup or Set. Hold down the key until the LED indicator turns red or blue.
After that, you will need to hold down the volume button. You will be able to see how the light bulb flashes at this moment. This indicates that the device has begun the procedure for selecting codes for the TV.
You will have to wait for a while, until you see the volume scale on the TV screen. When it appears, it will indicate that the configuration selection process is completed.
This is the last but not least step. You need to make sure that the TV remembers everything that you have done. To do this, press the settings key on the remote control again. If this is not done, then the configuration process will need to be carried out again.

Other methods for configuring devices can be found on the Internet, however, they are not so universal in themselves and are usually suitable for a certain model of remote control. Also, when you buy a remote control, it should come with a service book that will help you choose the right configuration.

This type of lighting is actively used in residential, office and even industrial premises. The most popular today are control systems implemented using radio switches, motion sensors, controllers with control panels, smartphones and computers. Modern technologies allow you to manage or on the adjacent plot, being hundreds of kilometers away from them. Some of them will be discussed in the article.

Remote Control Advantage

The use of remote control devices allows you to solve a number of problems:

Save energy;
Make the process of turning on / off lamps as comfortable as possible;
Protect your home or apartment from intruders (presence effect).

Types of remote control

Remote switching on of light can be wired and wireless, manual and automatic, with the ability to manipulate light from devices operating on the principle of emitting and receiving waves of certain frequencies: infrared, microwave, radio frequency, sound, ultrasonic, voice (control of specific commands). In this article, we will dwell on lighting control using various types of radiation, voice and sound commands.

Infrared and radio wave control of light from the remote control

Infrared lighting control using a remote control is extremely rare. Basically, such systems operate on the principle of signal transmission over a radio channel. To be able to manipulate light devices using an IR beam, a lighting remote control unit, for example BM8049M, is connected to the circuit break. It allows you to turn on the lamp switch with a regular TV remote control. To do this, point the remote control at the unit, press any key (which is not used to switch channels), after which the command is recorded in memory and now you can control the inclusion of the light without getting up from the sofa.

The main disadvantages of using IR light remote controls are the need for their accurate aiming at the signal receiver, since they only work within the line of sight, and the short range of the beam, but in this case repeaters can be used.

Much more widespread are light control systems using a remote control, in which a signal is transmitted from a control device to a controller that regulates the process of turning on / off the light at a certain radio frequency.

Radio control of light is more in demand for several reasons:

The ability to control the light not only with the remote control, but also with a computer, smartphone and other devices;
Signal range - about 100 meters in the absence of obstacles, 15-25 meters in the presence of obstacles;
The possibility of installing signal amplifiers and repeaters for better transmission of commands from the control device.

Remote lighting control system via radio channel using a remote control consists of:

Console;
battery;
Remote control controller connected to the network and load.

Install the controller into the wall or glass of the chandelier (see photo). It can control incandescent lamps, compact and conventional fluorescent, halogen, LED lamps, and not only single lamps, but also their group.

Remote control of light with infrared and radio switches

Infrared switches are a rarity in the lighting market, as it is more reasonable to control the light using radio devices. One of the most popular switches is "Sapphire" by Nootekhnika (Belarus). The same company produces a variety of radio lighting control devices, including those mentioned below. The switch is controlled by any remote control, for example, television or manually. The signal is received by a receiver located inside the device on the touch panel. A light switch with a remote control is shown in the photo.

Overview of the IR switch "Sapphire", video:

A light switch with a remote control is placed in any place convenient for them, power units - in a junction box or a glass of a chandelier.

An example of "binding" a lighting control unit to a radio switch, video:

Using sensors to control lighting

In the lighting market, various motion sensors are widely represented for remote control of lighting. The most common of these are infrared. They are devices that close or open the lighting circuit with an increase in the level of infrared radiation in their "visibility" zone. As soon as a person or animal enters the field of action of the sensor, whose body temperature is higher than the background temperature, the light turns on. As soon as a person leaves the sensor's coverage area or is in a stationary position for several seconds, the light turns off. Motion sensors are mounted most often in the entrances, above the front door, less often - inside the apartment.

Disadvantages and advantages of infrared sensors

The disadvantages of using motion sensors include the possibility of false alarms (reaction to warm air, sunlight), deterioration of outdoor performance due to precipitation, lack of operation of the device in the case when a person’s clothing does not transmit infrared radiation, constant switching off of the light after 10-15 seconds, as soon as motor activity decreases.

The advantages of sensors include the ability to control the consumption of electrical energy and, as a result, reduce cash costs, safety for human health, and ease of use.

Connecting motion sensors is not difficult; the installation diagram below is very common. For its implementation, a three-wire wire is required, with which the lighting control device is powered from the network and connected to the load. The phase wire of the network is connected to the phase wire of the sensor. Zero conductors of the lamp, power supply and sensor are connected together. The luminaire is connected by a phase wire to the remaining wire of the sensor.

Selection of infrared motion sensors

When choosing IR sensors, pay attention to the following parameters:

Place of application. Sensors are available with degrees of protection from IP20 to IP 55 and are built-in and mounted. For use in an apartment, a built-in sensor looks more profitable, and the degree of protection practically does not play a role. To install the device on the street or in the entrance, it is better to choose a model with protection against dust and water, mounted on a bracket;
Maximum range. IR sensors capture changes in background temperature at a distance of 10-20 meters. Those of them that are planned to be installed on the street should have a larger "coverage" radius. Indoors, this parameter is useless;
detection angle. In the vertical plane, the viewing angle of the sensors is 15-20 degrees, in the horizontal - from 60 to 360 degrees;
Load power. Before buying a sensor, you need to know the power of the load connected to it and choose a device according to these indicators with a margin.

Using other motion sensors to control the light

In addition to infrared controllers, microwave, sound and ultrasonic, as well as combined sensors are sometimes used to control lighting.

Microwave sensors

Microwave sensors work on the principle of emitting and receiving electromagnetic waves. In normal mode, the frequency and length of the waves emitted and reflected from objects are the same. When a person enters the sensor's coverage area, these parameters change, after which the light circuit switching mechanism is activated. The advantages of microwave sensors are that they are high-precision devices, they work perfectly even in bad weather, and the disadvantages are the possibility of false positives, high price, and harmful radiation for sensors with a large coverage radius.

Ultrasonic sensors

Ultrasonic sensors are similar in principle to microwave sensors. Inside these devices, a generator of sound waves is installed, with a frequency of 20 to 60 kilohertz, which are emitted and reflected from objects located in the field of the sensor. When a person or animal enters the coverage radius, the frequency of the sound waves arriving at the sensor changes, which the device immediately registers. Disadvantages of ultrasonic sensors: may not respond to smooth movement, cause discomfort to animals. Advantages of sensors: low cost, they work in conditions of high humidity, temperature changes, they react to movement, regardless of what kind of clothing a person is wearing.

Combined sensors

Combined sensors combine several motion detection technologies. They can use microwave and ultrasonic radiation or infrared and microwave. Such devices most qualitatively perform the tasks assigned to them.

Sound sensors

Sound sensors respond to sudden changes in sound, the level of which is set by changing the sensitivity of the sensor. Most often, the light is turned on and off by clapping your hands. A variety of sound sensors can also be considered voice switches.

Voice control of the light

Voice control of lighting devices in the apartment is implemented using voice sensors-switches, often used in Smart Home systems, as well as computers or smartphones on which a special program is installed.

Light switches with remote control (voice) are divided into two types: with the need to configure and without it. In the first case, you need to teach the device commands to activate, turn on and off the light, in the second case, all commands are already written in memory and indicated in the instructions, you just need to use them to control. Often such switches can be controlled not only by voice, but also by any remote control. These include Jaco and Servi. You can get acquainted with the features of their work on the websites of manufacturers.

Which gives out the code of the key pressed on the IR remote control via UART, it is not at all difficult to make firmware for direct kicking of the microcontroller with its feet. The only problem is that it is not known in advance which remote we will use or which key we will use. You will have to attach a piece to the program that allows you to study the necessary buttons. This is what we will do now!

Agree, it is very convenient when, without getting up from your chair, you can control, in addition to the TV, lighting, a fan or other household appliances in the room with one remote control. And if the device is difficult (or even impossible) to get to? Or you need a remote to control your model. It is for such purposes that this device is intended. To control the loads, any remote control you choose is suitable, on which you can select any keys. And if suddenly you cannot quickly find the remote control you left somewhere, you can use any other remote control that comes to hand, having gone through a simple procedure for studying it. In general, this is the right device. Let's collect!

Assembly of the device.
For the load control device, we take, previously made by us,. There is no need to redo anything - everything we need is already on the board.

Legs Load A, Load B, Load C are designed to control loads (how to connect the load to the microcontroller -). The indicator LED will display device activity.

Firmware.
To flash the microcontroller, all the necessary signals are displayed on the board. We connect the programmer and upload the firmware.
- Firmware load control device
- Fuse bits for device

Device operation.
The device works very simply. Before using the selected remote control, you must go through the procedure for studying it. By pressing the studied remote control buttons, you can control the loads: turn them on / off both individually and all together; remember and restore the current state.

The procedure for learning the keys of the remote control:
- turn on the device;
- for about 10 seconds, hold down any key on the remote control (for different remote controls, the hold time is different, since it is not the hold time that is measured, but the number of auto-repetitions of the button command);
- after 10 seconds, the indicator LED flickers - the device has switched to the study mode;
- then sequentially press the keys of the remote control in the order of the device functions. After each key pressed, the device will confirm the memorization of the button by blinking;
- after the last learned button, the device will confirm the end of the study of the remote control with a long blink and go into the load control mode.
You can study the commands of the remote control keys as many times as you like. The learned buttons are recorded in non-volatile memory, so the device will “remember” them even after the device is turned off.

The sequence of studying the remote control buttons:
1 load A on/off (Load A)
2 on/off load B (Load B)
3 load C on/off (Load C)
4 turn off all loads
5 turn on all loads
6 save load status to non-volatile memory
7 restore load state from non-volatile memory
There are 7 teams in total.

If you do not have the required number of free buttons on your remote, or you do not need some functions - just press the already learned key on the unnecessary function and this function will not be activated.

Video about how it all looks in reality:

P.S. This variant of IR-signal processing and studying remote controls will enter the 1W-IR network almost unchanged, i.e. each device on the network (if it needs it) will be able to receive, in addition to network messages, commands from IR remotes. The algorithm will still be refined, as it is not yet optimal and has not been debugged.

MODIFICATIONS.
(Change of some aspects of the device operation. The general logic of operation remains the same)

More modifications are possible. You can also show your modifications there.

Modification No. 1.
- Removed: launching the remote control learning procedure with a long press on any key on the remote control.
+ Added: launching the remote learning procedure when the leg of the crystal 6 (PB1) (or the pin of the Out board) is shorted to ground when power is applied. After switching to the learning mode (the indicator LED flashes), the leg must be “released”.

Modified firmware Mod1

Price: $3.92

Good afternoon friends! Not so long ago, I was puzzled by the next modernization of my home, namely the creation of a remotely controlled LED backlight. Details under the cut)

A short background: I live with my girlfriend, who, despite her full 20 years, the second year of a medical school with an anatomical and other charms and a fortress of nerves, is terribly afraid of the dark. Just to shiver. So much so that the moment between the flick of the switch and the fall of the body into a warm bed with an anti-monster blanket sends her into a slight tantrum. I thought that this would not work and solved the problem ingeniously, ordered the main character of this review.

Meet the load remote control module with an electromagnetic relay and a 433 MHz remote control.

Allows you to control a load of 10 A at a voltage of 250 volts. "But it is not exactly". It's the Chinese. However, I can say with confidence that the relay kept the load of 800-900 W for 2 hours absolutely without problems, I specially checked it before writing this review. In addition, this relay has been working for me for about a year to control the backlight of the table, and a similar module with the same relay works in the corridor, controlling the light bulb.

With the introduction on this and finish. Let's start looking at the relay itself.

We see 2 terminals: one for 2 wires and the second for 3 wires. Through the terminal block, 12 volts is supplied to 2 wires, and the second one is used to connect a controlled load. Now let's move on to considering the reverse side of the relay, in particular, the connection point of the triple terminal block.

The central contact (COM) is used to connect the input of an open circuit, and the NC and NO contacts, respectively, for the output of an open circuit to be closed. In this case, the NC (normal close) contact is closed in the off position of the relay, and NO (normal open), on the contrary, is open, and when the relay is turned on, they change places. This allows you to both turn on the connected load at the touch of a button, and turn it off.

Now let's look at the jumper and understand what it is for.

This jumper allows you to change the operating mode of the relay panel, choosing from 3 options.

1) In the case when the jumper is not installed at all: pressing button A closes the relay, and releasing this button opens the relay.
2) A jumper is placed on pins 1 and 2: pressing button A closes the relay, and pressing button B opens the relay.
3) The jumper is installed on pins 2 and 3: the first press of button A closes the relay, the second press of button A opens the relay, then in a circle.

Now let's look at the button to write the key fob to memory.

I didn’t have a chance to use it, so I quote the translation from the description on the product page:

1) To record a new key fob, hold the button for 3 seconds, then press the button on the key fob.
2) To clear all recorded keyfobs, hold the button for 8 seconds or more.

As for the range: it takes about 20 meters through 3-4 concrete walls without problems, in an open area about 50-70 meters without problems.

Summing up: I really liked the product, both for its appearance and for a large number of use cases. Now I use such a relay to remotely turn on the backlight in the room (about six months, no problems). In the future, I plan to make a remote electric fuse for pyrotechnics based on such a relay. By the way, the current consumption is stated by the seller of 6 mAh, according to my measurements, it turned out to be 4 mAh. This will allow you to make autonomous projects based on this relay. In general, I definitely recommend buying. Justifies its price.
