A large square light emitting diode. When connected to a power source emits weak colored light. The color of the light depends on the value of signal aplied to the diode. 0.8V or above produces light of 8 different colors. The light is too weak to light up the surroundings, but it's easily visible. Useful for creating color screens. It has inputs on all sides for easy connection and can be placed on any surface.
