An addressable RGB LED is a type of light-emitting diode that combines red, green, and blue LEDs into a single package, allowing each LED to be individually controlled for color and brightness through digital signals. Unlike standard RGB LEDs, which require all LEDs in a strip or array to display the same color, addressable RGB LEDs have integrated microcontrollers or chips that assign a unique address to each LED. This enables complex lighting effects, animations, and precise control over each LED's color and intensity, making them popular in decorative lighting, displays, and custom electronics projects. Addressable RGB LEDs are commonly used in gaming peripherals, smart lighting, and artistic installations.
