Required modulesIntegration

The OR Gate is a redstone circuit added by Project Red. It is a logic gate for complex redstone circuits. It emits a redstone signal, if at least one signals reach the gate (see Usage).

The circuit would be possible with Vanilla redstone mechanics, but this block reduces the size of the circuit to 1 block. This makes complex circuits clearer and easier to control. In electronics, this gate enables the physical execution of the Boolean function "OR".



An OR Gate with input and output sides indicated by WAILA

For an easier usage, NEI and WAILA could be installed, which show you the input and output on the OR Gate.

The OR Gate has three input sides and one output side for red alloy cables, redstone, an adjacent circuit, machine, lamp or anything that can be controlled with redstone signals.

If there is a redstone signal at least one input side, then a redstone signal is emitted on the output side. It makes no difference whether one, two or three signals reach the gate.

Using the screwdriver from Project Red, the orientation of the gate can be changed freely in all four directions. Furthermore, using the screwdriver in crouching, the input sides can be turned off and on again in various combinations.
