This tutorial goes over how to control an RGB LED with an Arduino ESP8266 ๐ฆ
Suppliesโ
- (1) LED - RGB Diffused Common Cathode
- (3) Resistor 220 ohm
- (4) Jumper wires
- (1) ESP8266 Wi-Fi Microcontroller (NodeMCU v3)
For refrence I have included the pinout diagram for the ESP8266 Wi-Fi Microcontroller (NodeMCU v3) that I am using.

Codeโ
This project does not require any additional libraries. The Arduino standard lib is enough.
int red_light = 0;int green_light = 4;int blue_light = 5;void setup(){ pinMode(red_light, OUTPUT); pinMode(green_light, OUTPUT); pinMode(blue_light, OUTPUT);}void loop(){ RGB_color(255, 0, 0); // Red delay(1000); RGB_color(0, 255, 0); // Green delay(1000); RGB_color(0, 0, 255); // Blue delay(1000); RGB_color(255, 255, 125); // Raspberry delay(1000); RGB_color(0, 255, 255); // Cyan delay(1000); RGB_color(255, 0, 255); // Magenta delay(1000); RGB_color(255, 255, 0); // Yellow delay(1000); RGB_color(255, 255, 255); // White delay(1000);}void RGB_color(int red_light_value, int green_light_value, int blue_light_value){ analogWrite(red_light, red_light_value); analogWrite(green_light, green_light_value); analogWrite(blue_light, blue_light_value);}
