DISCLAIMER:
This document is the result of an obscene amount of
work and research because I really wanted to make
a nice wood case / bezel using Ponoko for a project
I'm working on. Literally everything in this document
might be wrong and if you waste money or injure
somebody based on this document, it's your own
look out. If you can and want to correct any of the
information here, contact andrew@amorrow.com.

Notice the rowPins and colPins below in the sample code example:
// example from Arduino playground: http://www.arduino.cc/playground/Code/Keypad
#include <Keypad.h>
const byte ROWS = 4; //four rows
const byte COLS = 3; //three columns
char keys[ROWS][COLS] = {
{'1','2','3'},
{'4','5','6'},
{'7','8','9'},
{'*','0','#'}
};
byte rowPins[ROWS] = {5, 6, 7, 8}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {2, 3, 4}; //connect to the column pinouts of the keypad
