Pack of 5 RGB LEDs (Common Cathode) | 5mm Tri-Color LEDs for DIY Electronics, Arduino & Prototyping

This pack of 5 RGB LEDs (Common Cathode Type) is perfect for adding vibrant, full-color lighting to your electronics projects. Each LED contains three separate diodes (Red, Green, Blue) in a single 5mm package, allowing you to create a wide spectrum of colors by adjusting the current to each color channel.

These LEDs feature a common cathode configuration, meaning the negative terminal is shared among the three colors, making them compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers. Ideal for prototyping, hobby projects, decorative lighting, and educational experiments.

With the ability to produce any color by mixing the RGB channels via PWM (pulse-width modulation), these LEDs are a great tool for learning about LED control, color theory, and embedded systems programming.
