/Projects/Dual channel IR remote control v1

This project is very similar to previous one: IR light dimmer v1. The reason for building this device is primarily because incandescent light bulbs are being widely replaced with fluorescent power-saving ones. So the differences between dimmer and this device are that it has two channels, it can't be used for light dimming and it can control those power saving fluo-bulbs which have internal electronics/converters. The controlling element is solid state relay (SSR) which consists of opto-triac MOC3043 (MOC3042) and a triac (ie.: BTA16, BTA08, ...). This combination enables us to turn ON/OFF all kinds of appliances (motors, lights, heaters, boilers, PC...).

Features of current beta version of firmware:

- Controlling two independent appliances via remote controller and wall push-button
- Double-click on the push-button controls second channel B
- Learning IR codes from RC5 and NEC remotes
- Two modes of operation: Toggle and ON/OFF
- Sleep timer in duration of 2 minutes

If used for controlling the lights, this device is connected to existing home wiring installation inside a junction box which is usually located above the light switch. In order to properly connect the device to installation one should follow the schematics provided for that purpose. If connected differently there is a very big chance of some freaky side effects such as burned PIC microcontroller, serious fire and who knows what else.

Learning remote control IR codes (programming procedure)
After connecting the device to installation you must program all 5 buttons of the remote control. Here is how to do that:

1. Hold the wall push-button for 11 sec so that the device can enter programming mode. After those 11 sec, LED will start to blink fast and both channels will turn off. Now you have 11 sec to complete the programming sequence:
2. Press the first button on your remote that will turn on first channel (ON - A)
3. Press the second button on your remote that will be used to turn off first channel (OFF - A)
4. Press the third button on your remote that will turn on second channel (ON - B)
5. Press the fourth button on your remote that will be used to turn off second channel (OFF - B)
6. Finally press the fifth button that will be used for activating/deactivating sleep mode (SLEEP)

During programming the LED and channel A will blink to confirm IR code reception. If your remote control does not have all 5 buttons that you can use, you can repeat previous button but that will cancel out some features. For example if your remote has only two buttons [X and Y], and if during programming you press: X X Y Y Y, that means that key X will be used for channel A ON function, and key Y will be used for channel B ON function. In that case you must configure jumper Jp1 for Toggle mode so that you can also turn the channels OFF with the same buttons. If you choose combination X X X X Y, it means that the key X will be used for ON and OFF function of channel A, and key Y will be used to activate/deactivate sleep mode (channel B not used).
Programming notice: If during programming you notice that LED blinks even when you don't press any buttons on your remote control, it is probably because you used TSOP11xx instead of TSOP17xx receiver module. In that case you will probably not be able to program your device properly.
If you are not satisfied with your choice of remote controller buttons you can repeat the learning procedure as many times as you wish.
If you are planning to use your TV's remote controller you should probably choose those teletext buttons: red, green, yellow, blue and some fifth one, to avoid for example, switching channels when operating the device.

Appliance controlling
Connected appliances (or just one) can be controlled via the remote controller or the wall push-button.
- Remote controller can work in two modes: Toggle and ON/OFF mode (adjusted with jumper Jp1 in the schematics). Toggle mode is used to control the appliance with only one IR button in T flip-flop fashion: First press of a button turns the channel ON and second button press turns if OFF. ON/OFF mode requires at least two remote buttons, one to turn the channel ON and the other to turn if OFF.
- Wall push-button can control both channels (appliances). Single-click turns OFF all channels and another single-click turns ON those channels that were ON before turning them OFF. Double-click will turn ON all channels if both channels were OFF and if at least one channels was ON it will toggle the second channel. This might seem complicated but I assure you it is not.

Sleep timer
Sleep timer can be activated by a bit longer wall push-button press, more than 1.8 sec to be precise, or by pressing the appropriate button on the remote controller. Sleep timer cancellation is accomplished just like the activation. Please note that sleep timer will also be cancelled by turning any channel ON.

Important notice: This device is connected to mains power line, so it requires a lot of respect. If you are not sure in what you are doing, you better leave the installation part to the experienced electrician.

Actually, thanks for the link. That switch is great but it will not work with this circuit. Sorry... :)

Sorry for double post. This is no COMMERCIAL LINK. This is what I used: http://www.aliexpress.com/item/Free-Shipping-EU-Standard-VL-C701B-11-Door-Bell-Crystal-Glass-Sw itch-Panel-110-250V-Touch/720866308.html

Hi again. The schematic is working properly until I change the wall switch with an Touch Sense door bell (no more click-clak sound; it's capacitive touch). Not working anymore and I believe is because of the SW wire that has AC on it. That's why the touch sense door bell not working :). So i believe there is no way to NOT have AC on that wire? thanks !

Hello bluebear, it is normal that you lave a Line on the wire that goes to SW pin. The Line passes through PIC internals and when you test the SW wire you see Line there as well. Did you test the device on the desk before mounting on the wall? Warning: bBe careful not to shock your self while testing this device on the desk!

hello, question: I mounted a touch switch (door bell) in the wall and it's not functioning. I tested the Terminals in the wall ( the Line and the wire who goes to SW in schematic) and i have on both of them power (Line is normal to have AC but on the wire that goes to SW ???) . Is there any posibility to not have AC on the SW wire? I have to remove C5 ? thanks !

Hey. Great device. I assembled it, but it works only with remote control SONY. RC-5 or NEC not working ((

Pozdrav. Posto nijesam bas vezan za elektroniku a projekat mi se svidio tj ugradio bih 3 komada interesuje me da li je neko zainteresovan da to uradi i po kojoj cijeni. u zdravlje, Raco

Kondenzator C3 zamjeni sa 100uF (veci kapacitet). Otpornik R2 malo povecaj (ne znam koji si stavio) pa probaj! Takodje ne znam koje si koristio C1 i R1 ali prvo probaj sa ovim kondenzatorom C3 i otpornikom R2 da rijesis problem.

Imam problem koji se manifestuje na sledeci nacin. Programirao sam sve kako treba. Sijalica se pali sa daljiniskim upravljacem, medjutim nikako nece da se ugasi komandom sa daljinskog upravljaca. Ne znam u cemu moze biti problem.
