// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
8,4,4,8,4,2,2,

};

void setup() {
  // iterate over the notes of the melody:
  for (int thisNote = 0; thisNote < sizeof(noteDurations)/sizeof(noteDurations[0]); thisNote++) {

// to calculate the note duration, take one second 
    // divided by the note type.
    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
    int noteDuration = 1000/noteDurations[thisNote];
    tone(pin, melody[thisNote],noteDuration);

// to distinguish the notes, set a minimum time between them.
    // the note's duration + 30% seems to work well:
    int pauseBetweenNotes = noteDuration * 1;
    delay(pauseBetweenNotes);
    // stop the tone playing:
    noTone(pin);
  }
}

void loop() {
  // no need to repeat the melody.
}
```

最好是先把例程中的toneMelody的进行修改，然后另存为。这样这个程序所需要用的pitches.h头文件就会自动复制出来。这个程序的硬件接法是把喇叭的两条线中的一条接到了GND，一条接到了3（播放Melody，ART目前支持2和3pin）。另外接3 pin的线最好能够接一个100欧电阻，不接有烧掉的危险。
