This is a projects similar to few others, just a little bit changed and easyer to make!

Step 1: Wiring!

You need :

1x Arduino Uno

1x 4x4 Keypad

1x 1602 LCD Display

Jumper wires

THIS REQUIRES SOLDERING! WE ARE NOT GOING TO COVER IT IN THIS VIDEO!

Wiring:

I made it clearly in the schematic

Step 2: Coding!

There's nothing to really cover there, for help and if you want some info about the code let me know.

Let's move to next, FINAL step.

"A" = Addition

“B” =Subtraction

“C” = Multiplication

“D” = Division

“*” = Clear

“#” = Equals
