4 Bit Adder

This project is a 4-it adder

A 4-bit adder is able to calculate the addition of 2 4-bit number and display the answer on LEDs

You plug in your 2 4-bit numbers by flipping the dipswitches on, or off. (on meaning a 1 and off meaning a 0)

• Arduino Uno
• Bread Board
• LED (Yellow, Red)
• 2x Dip Switches
• 2x XOR Logic Gates
• 2x AND Logic Gates
• 1x OR Logic Gate

Here you can see the wiring of this circuit a bit more clear

I've also added some of the progression steps of making the circuit in real life, and how the logic works for the circuit
