Simon Says is a memory game. Start the game by pressing one of the four buttons. When an LED lights up, press the button matching the LED.

This code generates random sequence, plays music, and displays button lights.

Ported for the ATmega168, then ATmega328, then Arduino 1.0. Fixes and cleanup by Joshua Neal <joshua[at]trochotron.com>
