The double OR Bit is a logic gate with two inputs and one output. In order for the double OR gate to output an ON signal, the first input, the second input, or both inputs need to be ON. When both inputs are OFF (inactive), the output is OFF.Building circuits with logic Bits is essentially the equivalent of physical prograqmming. Logic Bits create rules for your circuit to follow, giving you more ability to create interesting and complex interactions. The double OR Bit is good option for projects where you want to detect two inputs but don’t care which input is activated.
