We have three circuits made with NAND, one with the same result of doing an OR, another one to AND and the last one to NOT

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.

Little circuit for auto door, 3 inputs, 1 output

NOT gate, AND gate (x2), OR gate

A simple 8-bit arithmetic logical unit.

The following commands are implemented:

Logic Operations:

[0] 000: OR

[1] 001: NAND

[2] 010:NOR

[3] 011: AND

Arithmetic Operations:

[4] 100: ADD

[5] 101: SUB

The two's complement for subtraction is implemented with a NOT Gate and an adder (which simply adds 1 to the negated input).
