ESP8266 WiFi Module Control RGBLED

ESP8266 WiFi Module Control RGBLED

This project we use ESP8266 WiFi Module to control RGB LED via WiFi Network.

System Diagram


1.ESP8266 WiFi Module ( or NodeMCU )
2.RGB LED ( common anode (A) ) if you to use common cathode ( K ) must edit code.
3.OLED Display ( Option )

Wiring Diagram ( RGB LED Common Anode + )

ESP8266 Pin GPIO_14 to LED R
ESP8266 Pin GPIO_12 to LED G
