For this project, you will need a 4x4 keypad, breadboard, arduino and 8 wires.
Shape Your Calculator
Lay out your calculator and organize your work, even though it does not have much of an impact here, in some other project it will.
Add the Code Into the Arduino

All the explanations are in the code.
The code is pretty large but it is relatively simple, here is the link for the arduino project.

Create Your Own Version
You can modify the code as much as you want. The basic idea is in the code and you can make your own version, building off of the calculator I have made.
Thank you for reading and following the instructions!
