I created this Color LED Controller App around 2015 and it already hit 100K+ download.
Just want to share it with you!
174 countries / regions!
This App only work with Arduino, ESP8266, or ESP32 + Bluetooth + RGB LED!!
It does not work with commercial RGB LED.
All the project detailed can be found from here:
