// Simple test program for new PS2Keyboard library
// Connect a PS2 keyboard to pins 3 & 4 (CLK and DATA respectively) and supply 5V to the keyboard
// For examples, see here: http://www.arduino.cc/playground/ComponentLib/Ps2mouse
// or                here: http://www.beyondlogic.org/keyboard/keybrd.htm
// That second article is a great place to start if you want to understand whats going on
//
// When you've compiled the code and uploaded it to the board, start a serial monitor at
// 9600bd.  Then press keys on your PS2 keyboard (the one connected to Arduino, not the one
