DIYables RGB LED for Arduino, ESP32, ESP8266, Raspberry Pi, Common Cathode
Click to zoomQuick Overview
This DIYables RGB LED set includes 50 pieces of 5mm multicolor LEDs with common cathode configuration for Arduino, ESP32, ESP8266, and Raspberry Pi projects. Each LED contains red, green, and blue elements that can be independently controlled to create millions of color combinations.
The common cathode design connects the negative terminal of all three LED elements together, requiring separate PWM control on the positive pins for each color. Operating at 1.8-3.4V with 20mA current, these LEDs provide 4-5 lumens brightness with 120-degree viewing angle. Available in both water clear and diffused lens types.
Ideal for color-changing displays, mood lighting, status indicators, RGB lighting effects, decorative projects, and interactive visual feedback. The PWM control enables smooth color transitions and brightness adjustment for creative lighting applications.
