Like what we heard in the song The Color of The Night, we always indulged in the psychedelic lights at night. The colorful lights tell sadness or happiness. I like the color of lights but I hate the uncomfortable manually switch of them. Fortunately, I have DIY a smart colorful light which satisfied my requirements of switch, color and even feelings.

Hardware in need:

RGB LED Light×12

NPN Triode×1

FireBeetle Board-ESP32×1

FireBeetle Covers-Proto Board×1

Rotary Encoder EC11J×1

BME280×1

Caution: You can go to DFRobot official web to buy electronic components.
