noTone()
Descripción
Detiene la generación de una onda cuadrada disparada po tone(). No tiene efecto si no se está generando un tono.
NOTA: Si desea reproducir tonos diferentes en varios pines, es necesario llamar noTone() en un pin antes de llamar a tone() en el siguiente pin.
Sintaxis
noTone(pin)
Parámetros
- pin: el pin en el que se está generando el tono
Retornos
- Ninguno
Ejemplo
Let's to play "Jingle Bells" song with Arduino.

int noteDuration = 1000 / noteDurations[thisNote];

// to distinguish the notes, set a minimum time between them.
// the note's duration + 30% seems to work well:
int pauseBetweenNotes = noteDuration * 1.30;
delay(pauseBetweenNotes);
// stop the tone playing:
noTone(8);
}
}
void loop() {
// no need to repeat the melody.
