Addressable RGB LED Controller is a device used to drive "addressable LEDs / addressable LED strips." Unlike ordinary RGB controllers, it allows each individual LED to change color independently, enabling effects such as flowing water, rainbow gradients, running lights, music synchronization, and pixel animations.
Each LED on an addressable strip has a built-in driver IC (e.g., WS2812B / SK6812 / WS2811 / WS2813 / WS2815 / APA102 / SK9822). The controller sends digital signals via a data line:
WS2812B / SK6812: Single-wire data (DIN → DOUT cascading)
APA102 / SK9822: SPI two-wire (DATA + CLK)
DMX512: Used in stage/professional applications; differential A/B signal + decoder
Each LED receives its own 24-bit data (8 bits each for RGB), latches the values, and displays the color — hence the term "individual pixel control."
