This project is going to combine a 4bit adder with an lcd display by showing the decimal values of the circuit on the display when a certain switch is turned on.

Supplies

1. Arduino

2. Breadboard

3. 4 different coloured wires

4. 2 dip switches

5. 2 XOR gates

6. 2 AND gates

7. 1 OR gate

8. LCD monitor

9. 8 10K ohm resistors

Understanding of 4 Bit Adder

Once all components are placed correctly you can now begin wiring the circuit. When wiring make sure you are placing them in the correct spot as one wire can mess up everything.
