/Projects/IR light dimmer v1

This is a very simple IR light dimmer that you will wish to have sooner or later, especially those who are lazy enough to get up and turn off the lights. There are two versions of PCB for two sizes of capacitors, so PCBs are: 32.5 x 26.5mm and 28.5 x 27mm.
You can download the project files at the bottom of this page by clicking on red "download" button.

Features of current beta version of firmware:

- Soft start (gradually turning on the light bulb)
- Soft down (gradually turning off the light bulb)
- Learning IR codes from RC5 and NEC remotes
- Dimming in 10 levels by using only IR remote
- Previous dimm-level remembering when operating with remote
- Sleep timer in duration of 1.6min for 60Hz version and 2min for 50Hz version
- ON/OFF control with wall pushbutton

Dimmer 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 dimmer 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 dimmer to installation you must program the remote control buttons. Here is how to do that:

1. Hold the wall pushbutton for 11 sec so that dimmer can enter programming mode. After those 11 sec, LED will start to blink fast, and light will dimm to third (3.) level. Now you have 11 sec to complete the programming sequence:
2. Press the first button on your remote that will increase light level or turn on the light when it is turned off (ON/UP)
3. Press the second button on your remote that will be used to decrease the light level (DOWN)
4. Press the third button that will be used for activating/deactivating sleep mode (SLEEP)
5. Finally, press the fourth button that will be used to turn off light completely (OFF)

During programming, both the light bulb and LED will blink to confirm IR code reception. If your remote control does not have all 4 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 (A and B), and if during programming you press: A A A B, that means that key A will be used for ON/UP function, and key B will be used to completely turn off the light. If you choose combination A B B B, it means that the key A will be again used for ON/UP function, and key B will be used to decrease light level (it will also turn the light off completely in 10 button presses - until zero level).
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 dimmer properly.
If you are not satisfied with your choice of remote controller buttons, you can repeat the learning procedure as much as you like.
If you are planning to use your TV's remote controller, you should probably choose those teletext buttons: red, green, yellow and blue to avoid, for example, switching channels when operating the dimmer.

Sleep timer
Sleep timer can be activated by a bit longer wall-pushbutton 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. It is possible to increase/decrease the light level when sleep timer is active. Dimmer will automatically set the light level to six (6) when entering the sleep mode, but only if previous level was greater than 6.

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.

Note: Dimmer works better with TIC206 rather than TIC216!

You will have problems with other triacs, so there is really no direct replacement. If you want, you can use MOC3023 plus any other triac you can find and then it should work.

its almost finish! but i have no luck finding tic 206 or tic 216. can you recommend other possible triacs that i can use for 220v/60hz? please help me master trax.

Yes, you can use those capacitors...

is is ok to use MKP or MKS type capacitor for C1 coz i cant find MKT type. im just starting to build this project. this project is awesome! thank you for being soooooooo intelligent and generous master trax.

Dom je resio problem dimera koji mu daje 130v tako sto je imao srecu da nadje tic206m koji moze da se ukljucuje preko 820 oma na gejtu. Ja sa skoro napravio ovaj dimer i isto mi se ponasao kao kod Doma i verovatno kod vecine koji su ga pravili tacno po shemi.Otpornik od 820 na gejtu je dobar za savsen tic206m ali za malo losiji mora se smanjiti na 510 oma koliko sam ja stavio i dimer mi savseno radi.

Sad vidim ogg za led... I ne razumem ga. U celoj toj prici ja nemam trafo, led su na 220V, kao halogene. verovatno se napajaju nekom rc vezom... znaci nije trafo...

Kao sto sam i mislio, cela serija trijaka je losa.. sreca pa sam samo 3 komada uzeo. Stavio 206m iz druge serije, raadi savrseno ;)

Mozes dimovati LED-ice, ali tako sto ces trafo da stavis prije dimmera. Znaci i dimmer trebas napajati poslije trafoa! Tako ces morati prepraviti i one C1 R1 komponente (smanjiti) da mogu napajati dimmer.

Kupicu danas pa proveriti. Nego, da li ja mogu sa ovim da dimujem led osvetljenje na 220, bez trafoa, znam da ne moze biti induktivni load... I jel moze da se prevazidje to nekako, da moze da se kontrolise trafo? Znam da je bilo da ne moze zbog nedovoljne struje sa pica na gejt neki drugi trijak, jel nadjeno resenje u medjuvremenu?
