The RGB LED (or Red-Green-Blue Light-Emitting Diode) Bit is a light with adjustable colour. You can use the purple littleBits screwdriver to turn the dials and create your own custom colour mix of red green and blue.
HOW IT WORKS
The RGB LED is actually 3 very small lights (a red a blue and a green light). Turning the dials changes the brightness of each light. The colours from these lights mix together to create every colour in the rainbow.
