The bargraph shows you how much signal the Bit is receiving with a display of 5 light-emitting diodes (LEDs) in different colors. Try it with a dimmer to make your own adjustable lamp.
HOW IT WORKS
The bargraph uses 5 LEDs to turn electricity into light. Each LED on the board needs a certain amount of signal in order to light up. As you increase the signal sent to the bargraph more LEDs will shine.
