An OR gate is one of the 2 fundamental gates in minecraft, which turns active when at least one of the inputs are active. An OR-gate has no delay.

AboutEdit

The constructing of an OR-gate is as simple as connecting a wire to the inputs. The wires can also point to a powered block, and signal of the block will then be your output, though a torch or repeater will be required to gain access to that signal. Thus unless one wants isolated inputs and/or outputs, a normal wire is the best option, as it has no delay.

FormulaEdit

As a fundamental gate, along with the NOT-gate, every boolean expression will be simplified to a combination of this gate and the NOT-gate. In formulas, it's written as

A+B

or

A OR B
