littleBits Double OR

The Double OR Bit is a logic gate with two inputs. Just like its name, if input one OR input two is receiving an ON signal, then it sends an ON signal from its output.

Picture a house that has a doorbell at the front door and a doorbell at the back door. Both doorbells are connected to the same buzzer inside the house. This buzzer will ring when EITHER OR BOTH of the doorbells are pressed.
