RGB Tri-Color LED 4-Pin (5mm) is a multi-functional light-emitting diode that combines three primary color channels—Red, Green, and Blue—into a single package. By controlling the intensity of each channel, users can blend these colors to produce a virtually unlimited spectrum of colors. This makes it an excellent choice for both functional and decorative lighting applications.
This LED comes in a 5mm through-hole package with four pins: one common terminal (available in either common anode or common cathode type) and three independent pins dedicated to the red, green, and blue channels. The LED features a clear epoxy lens, which ensures efficient light emission, high brightness, and long-lasting performance.
Using simple electronics or microcontrollers like Arduino, ESP32, or Raspberry Pi, you can apply PWM (Pulse Width Modulation) to the pins, enabling smooth color transitions, fading effects, and even complex lighting animations.
The RGB Tri-Color LED 5mm is widely used in:
- DIY hobby electronics and prototyping
- Arduino and microcontroller projects
- Robotics and sensor indication
- Decorative and ambient lighting solutions
- Multi-color indicator systems
- Experimentation with color mixing and display systems
Compact, durable, and versatile, this LED is a go-to component for students, hobbyists, and professionals working on interactive and visually appealing electronic projects.
