An arduino keypad tutorial that will show how the keypad works, how to wire it up and also how to use it with an arduino nano (it's the same way for arduino uno).
First we are showing the basics of how the keypad works.
Then we connect it to an Arduino Nano and use the library Keypad to demonstrate it operating.
We are demonstrating it on a 4x4 keypad but it's behaves the same on a 3x3 keypad.
This is part of our Ardino Basics tutorials.
