The bargraph is one of our favorite Bits: it has five LEDs in different colors that light up to show you how much signal the module is receiving. Try it with a pressure sensor to make your own strength-o-meter.
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.
