I wanted a switch for my Philips Hue lights but I did not want to spend $20+ for the one I could buy from Amazon. Not to mention, building it was fun.
This is a pretty simple project. Code is up on Github, linked on the left. Pics are obvious.
There's a rotary encoder with a pushbutton. Pushbutton does on/off. Rotation adjusts dimming.
Enjoy this project?
