How to control AC fan using Arduino


#1

Hi,
I want to control AC fan speed for my house using arduino, but I don’t have idea which kind of electronics should i use for the task. Can anyone help me.

HI,

This is a great project!
the most basic circuit you’ll need include a controller (all we offer would work, I recommend Arduino Uno for beginners), and an IR LED transmitter. You would also want to have some kind of input sensor as a trigger (could be buttons).
This would be enough if you know you AC IR codes, if you don’t you’ll also need an IR receiver.

Here is a good reference to start with: https://www.circuito.io/blog/gesture-remote-control/.
In this project the trigger is a Gesture sensor, feel free to change it.

Enjoy!
