this teaching tool allows different logic gates to be wired together with patch cables. While [David] first thought to use 74-series logic circuits directly, a much more versatile solution was to ...

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.

Computers use electrical circuits which have two states – on or off. This can also be represented as 1 or 0 or True and False. Logic gates take an input of True or False and give an output of ...
