An RGB LED has 4 pins, one for each color (Red, Green, Blue) and a
common cathode. It has three different color-emitting diodes that can be combined to create all sorts of color! Any color is possible depending on how bright each diode is. In this tutorial you will learn how to use an RGB LED with Raspberry Pi and create unique color combinations.
