representing the logic 0 and the logic 1, respectively. The AND gate has two inputs A and B. The output of the gate, A.B, depends on the two inputs according to the truth table at the right.

Building logic gates out of ... When two soldier crabs are placed at the top of the ‘Y’, they move forward until they meet and exit the maze through the output. This idea can be expanded ...

Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following examples. Transistors make up gates, gates make up circuits, and circuits make up electronic systems.

An AND gate usually has two inputs. AND tells us that both Input A AND Input B have to be 1 (or ON) in order for the output to be 1. Otherwise the output is 0.
