 Two motors attached to the motor shield.
 speaker/piezo for sound
 
 Arduino Uno has three timers; timer 0, timer 1, timer 2,
 Timer 0 is used by the arduino for millis().
 The motorshield uses timer 2, for pwm on pins 3 & 11.
 Since the standard arduino tone function uses timer 2 also, 

// without stopping everything for a delay.
