622 Full Adder

622 : Full Adder

Design render

How it works

there are total of 3 inputs, the first two inputs are 1 bit inputs and they are added. the third input represents the carry value.

How to test

input your 1 bit values to be added to the first two inputs

External hardware

Two LEDs are being used, along with two XOR, two AND, and one OR gate
