AC LED Dimmable Bulb Light Dimmer with Node MCU v2

I want to create a LED dimable drive circuit that can control by Node MCU output or use with arduino
uno r3 .What should I do?

  1. Find circuit and build an AC dimmer with NodeMCU.
  2. Add Blynk to control your project (easy step usually) :wink:

i have tried it with 0 cross detection but not working any example will be appreciated

Old topic.

Google for examples and use a slider in place of potentiometer.
