RGB LED

An RGB LED (Red, Green, Blue LED) is a light-emitting diode that contains three different colors of LEDs—red, green, and blue—in a single component. By controlling the brightness of each color, an RGB LED can produce many different colors, such as yellow, purple, cyan, and white. It can be controlled using a microcontroller like Arduino to create colorful lighting effects and visual indicators. RGB LEDs are commonly used in decorative lighting, traffic indicators, displays, smart lighting systems, and electronics projects.
