When the XOR Gate has only 2 inputs, it is a "one and only one" gate. However, when the XOR Gate has more than 2 inputs, it is no longer a "one and only one" Gate... It is no longer about exclusivity, it is about detecting an odd number of TRUE inputs.

This project "The Exclusive Gate" is about a circuit that has more than 2 Inputs (4 in this example) and only outputs TRUE if "one and only one" input is true.

First attempt at Half Adder. A half adder is a logical circuit that adds to one bit binary numbers and results into a two digit output.

My first attempt at an full adder. This is a logical circuit that performs an addition operation on three one bit binary numbers. The full adder produces a sum of three inputs and a carry value.
