RGB LED - 5mm - Common Cathode

A Light-Emitting Diode (LED) is a semiconductor-based light source that emits light when an electric current passes through it. As electrons move through the material, they recombine with electron holes, releasing energy in the form of photons. The color of the emitted light depends on the bandgap energy of the semiconductor. White light is typically produced either by combining different colored LEDs or by applying a phosphor coating that converts the light into a broad-spectrum white glow. This efficient lighting technology is widely used due to its low power consumption, long lifespan, and versatility in various applications.
