This module works on PWM ( Pulse Width Modulation Control ) in simple words we decrease or increase the duty cycle to set the intensity of the LED.

PWM is also used to

  • Control dimming of RGB strip.
  • Control the direction of the servo motor
  • Control the speed of the motor

The main advantage of PWM light dimmer is that it very energy efficient.

Parts Needed

You need to have the following parts

  • Arduino (Any version)
  • 1x AC Light Dimmer Module 1 Channel
  • 1x 220V/110V LED
  • Jumper Wire

Arduino Setup

Schematics For Arduino

Assemble all the parts by following the schematics below:


AC light dimmer schematic

Connect the LED lamp to the AC Load and dimmer to the AC input.


Coding Arduino

Note: There is a different setting for 50Hz and 60Hz supply. Change the values in the code accordingly.

  • Adjust the Dimming Range accordingly ( For us 880 to 902 worked).
  • Upload the code to the Arduino.
