The long LED is a flexible lighting option. We call it the long LED because the light is connected to the board by a cable which lets you put the light in some interesting places. One of our favourite tricks is to place the LED in the middle of a foam ball to make it glow!
HOW IT WORKS
This Bit uses a light-emmiting diode (LED) to turn electricity into light. The more signal you send the Bit the brighter the light shines.
