Device Control
Keypad is a library for using matrix style keypads with the Arduino.
As of version 3.0 it now supports mulitple keypresses. This library is based upon the Keypad Tutorial. It was created to promote Hardware Abstraction. It improves readability of the code by hiding the pinMode and digitalRead calls for the user.
