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.

                          

This esp32 project is based on FireBeetle ESP32 IOT Microcontroller (Supports Wi-Fi & Bluetooth).

Hardware in need:

RGB LED Breakout (5050)   

NPN Triode×1
        

FireBeetle ESP32 IOT Microcontroller (Supports Wi-Fi & Bluetooth) ×1
   

FireBeetle Covers-Proto Board×1
        

Rotary Encoder EC11J×1

BME280×1


Hardware Connection


Schematic and drawing, shown as below.




Firstly, connecting D2, D3, D4 to D2, D3, D4 of the FireBeetle Board-ESP32 respectively and drive with high-level. And connecting Vcc to Vcc of the FireBeetle Board-ESP32 too. Then, there are A and B in the Rotary Encoder EC11J, A should be connected to D7, B to D6 and the bottom should be connected to D5. Finally, connecting BME280 to I2C of FireBeetle Board-ESP32. 

   
 
 2. Connecting and fixing RGB lights with Dupond, shown as below. 


3. Connecting output line to FireBeetle Board-ESP32, Rotary Encoder EC11J and FireBeetle Covers-Proto Board according to the schematic and drawing, shown as below.

Remember to fix the connected electronic circuit with hot-melt glue.
