I am working in version 1.0 of the Arduino IDE under Lubuntu and my sketch calls in these libraries:

#include <Keypad.h>
#include <LiquidCrystal.h>
#include <math.h>

So others have done much of the hard work. The keypad.getKey() method does the donkey work, with no need to worry about rows and columns.

Why reinvent the wheel? Think of the code written by others as libraries.

Are you thinking of bringing the finished product to work or school for everyday use?
