SimpleKeypad is an Arduino library for using matrix keypads.
SimpleKeypad is based on the original Keypad library, but it is a simplified version. It does not support mutiple keypresses. It requires less memory and runs a bit faster.

This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
