The Red-Green-Blue (RGB) LED has three different LEDs in one bulb. Use the small switches to turn on each of the different LEDs, and control the red, green, and blue lights. Try mixing the colors together to get different combinations for purple, teal, and yellow lights.

The RGB LED Cube is just one part of a circuit. Add a battery to power your creations, a motor to make them move, and a switch to take control!
