Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Wiring!
You need :
1x Arduino Uno
1x 4x4 Keypad
1x 1602 LCD Display
THIS REQUIRES SOLDERING! WE ARE NOT GOING TO COVER IT IN THIS VIDEO!
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.
Step 3: Almost Done!
"A" = Addition
“C” = Multiplication
