The OR Gate has two inputs and one output. The output will turn on when either input A and/or B are turned on. This logic gate can be used for simple circuitry such as opening and closing doors. Two wires can be connected to one wire using this gate.
This item is not used much. When it is used, it is only for advanced conveyor systems for wood.
Signal Inverters and OR gates put together can make a NOR gate.
A = Left input, B = Right input;
0 = Off, 1 = On
