Highlights:
Microchip microcontroller with a Zero-Cross Detector (ZCD): PIC16F1703.
Leading edge (triac).
Main supply : 110V or 230V.
Automatic selection 50/60 Hz.
Adjustable resolution ( switch 50/102 , 37 to 206 by soft ).
Automatic learning of infrared remote control:
   - Pulse distance modulation 6 to 48 Bits ( NEC,JVC,RCA,Mitsubishi,Panasonic....).
   - Pulse Width Modulation Sony 12/15/20 bits.
   - RC5 Philips.
   - RC6 Philips.
Up to 6 keys : ON/OFF,Down,Up,Favorite1,Favorite2,Delayed Shutdown.
Gradual switching ON/OFF.
Delayed Shutdown ( 10 minutes @ 50 Hz ).
Minimum and maximum lighting adjustment ( Rotary encoder version only ).

The dimmer uses a microchip PIC16F1703 microcontroller with a Zero Crossing Detector input ( ZCD), which simplifies the hardware, only two resistors and one capacitor are required!!.
For PIC fans like me, I wrote the entire program in assembly (*.asm and *.s MPLAX V5.30 / MPLABX V6.00), the source and hexa files are available for download.
I offer two versions of equipment:
   - Lite version with a push button placed under the box allowing you to turn the lamp off or on and configure the dimmer with the remote control.

   - -A rotary encoder version which also allows you to adjust the lighting of the lamp and access to the mini and maxi setup.

How to :
Learning the remote control:
1-Press the push button until the LED is green ( Press the push button to exit ).
2-Press a button on your remote control until the LED is red.
3-Wait for the LED to turn green.
If the LED remains red this means that the remote control protocol is not recognized and the dimmer has restarted.
4-Press the button on your remote control which will correspond to ON/OFF,the LED turns red.
5-Wait for the LED to turn green.
6-Press the button on your remote control which will correspond to Down,the LED turns red.
7-Wait for the LED to turn green.
Repeat 6 and 7 for the Up,Favorite1,Favorite2,Delayed Shutdown keys.
At the end the LED remains red and the dimmer restarts.

Favorite lighting setup:
1-Press the button on your remote control corresponding to favorite 1 until the LED is red.
2-Adjust the lighting using the Up/Down buttons on your remote control.
3-Press the button on your remote control corresponding to favorite 1 to  save.
Same thing for the favorite2.

Minimun/Maximun lighting setup ( Rotary encoder version only ):
1-Press the push button until the LED is red.
2-Adjust the minimum with the rotary encoder.

3-Press the push button to save.
4-Adjust the maximun with the rotary encoder (no flickering).
5-Press the push button to save and the dimmer restart.

What do you need ?
   - Sprint Layout 6 ( PCB and BOM )
   - A PIC Programmer ( PICKIT3 or else )

Have fun with this project !!!
