Description
These 5mm RGB LEDs feature a diffused lens and a common cathode (longest pin) design, perfect for producing smooth, blended colour effects.
Each LED combines red, green, and blue elements in a single package, allowing you to mix nearly any colour by adjusting brightness levels using PWM or digital signals.
Ideal for use with Arduino, Raspberry Pi, ESP32, and other microcontrollers or shift registers in DIY electronics, displays, and lighting projects.
