arduino蜂鸣器两只老虎歌曲代码

好的，以下是用Arduino控制蜂鸣器演奏《两只老虎》的代码：

int melody[] = {
  NOTE_C4, NOTE_C4, NOTE_G4, NOTE_G4, NOTE_A4, NOTE_A4,
  NOTE_G4, 0, NOTE_F4, NOTE_F4, NOTE_E4, NOTE_E4,
  NOTE_D4, NOTE_D4, NOTE_C4, 0, 0, 0
};

int noteDuration[] = {
  4, 4, 4, 4, 4, 4,
  2, 4, 4, 4, 4, 4,
  4, 4, 2, 4, 4, 4
};

void setup() {
  pinMode(9, OUTPUT);
}

void loop() {
  for (int i = 0; i < 18; i++) {
    int duration = 1000 / noteDuration[i];
    tone(9, melody[i], duration);
    int pauseBetweenNotes = duration * 1.30;
    delay(pauseBetweenNotes);
    noTone(9);
  }
}

希望能帮到你！
