Arduino 220v AC dimmer with remote control with code

8/30/2017 05:16:00 PM  Simple Projects  

This Arduino project help you to control brightness of a 220V dimmable lamp or speed of ceiling fan (or any other electric motor) with an IR remote control using Arduino.
Max. power which can controlled with this dimmer depend on triac model.(BT136 can bear 4A according to Datasheet).

This project consist of 4 basic parts:

1-Microcontroller(Arduino)
2-Zero-cross detector(Bridge and Optocoupler)
3-Display(7Segment)
4-Phase angel controller(Tiac and Triac driver)

The load can controlled by Up and Down bush button or with IR remote controller.

Parts list:
Arduino UNO https://goo.gl/XR3mXG
Optocoupler pc817
Triac driver MOC3021(Or any other Random-phase triac driver)
1 Digit 7 Segment common cathode
Triac BT136
Diode bridge(4pcs 1N4007) (Diode kit: https://goo.gl/w1rmcX)
Push button(4pcs)
Resistor kit https://goo.gl/p4JvQY
Resistor 100K(2pcs)
Resistor470 ohm (2pcs)
Resistor 330 ohm
Resistor 100 ohm 1W
Resistor 10K
Capacitor 100nF 400v
IR receiver 1830B
Important NOTES:
1- You have to using only RANDOM-phase triac driver such as MOC 3021 or MOC 3023 , etc, and don't use MOC3041 or other triac driver with Zero-cross detector.
2-This project directly connected to 110/220v AC so can be very dangerous for beginners.
3-Red components(100 ohm resistor and 100nF capacitor) shown in the diagram should only used when the load is inductive.
4-Don't use this Dimmer for non-dimmable load such as CFL lamps, dimming can burn your lamp.
5-The number after "Case" in the code need to change with number that shown to you in "Serial Monitor" when you press a button on your remote control toward the IR receiver .
