Arduino Power Hour Revisited

/* A revamped power hour sketch.  One shot of bee... I mean soda
every minute for an hour [every time the speaker beeps]. -- Hook an 8 ohm speaker to pin 8 on the
arduino.  This sketch will increase the pitch of the tone with each drink.  This will kind of give you an idea of where you are in the hour.  It also buzzes twice at the end, signifying that you are done.

int pitch = 300; // Set initial Pitch to 300hz.
int audioPin = 8; // Set audio pin to 8.
int counter = 0; // Set counter at 0.

void setup(){
}

void loop(){
  counter = (counter + 1); // Increment the counter by 1 each time the program loops.
  tone(audioPin, pitch, 300); // Play the tone for 300ms.
  delay(59700); // Delay figured for 1 minute - the 300ms.
  pitch = (pitch + 10); // Increase the pitch.

  if(counter == 60){ // When the counter gets to 60 or 1 hour...
    tone(audioPin, 1000, 300); // Play an extra tone.
    pitch = 300; // Reset pitch.
    counter = 0; // Reset counter.
