先透過這程式碼做音樂

#define NOTE_C5 523
	#define NOTE_E5 659
	#define NOTE_G5 784
	#define BUTTON 2
	#define BUZZER 8
	int melody[] = {
	NOTE_E5, NOTE_E5, 0, NOTE_E5, 0, NOTE_C5, NOTE_E5, 0, NOTE_G5
	};
	int noteDurations[] = {
	10, 10, 10, 10, 10, 10, 10, 10, 10
	};
	int pin;
	int ledArrayHigh;
	int ledArrayLow;
	boolean mode = false;
	boolean buttonPressed = false;
	void setup()
	{
	delay(1000);
	pinMode(BUTTON, INPUT_PULLUP);
	for (pin = 3; pin < 14; pin++) {
	pinMode(pin, OUTPUT);
	}
	for (int thisNote = 0; thisNote < 9; thisNote++) {
	int noteDuration = 1000 / noteDurations[thisNote];
	tone(BUZZER, melody[thisNote], noteDuration);
	int pauseBetweenNotes = noteDuration * 1.30;
	delay(pauseBetweenNotes);
	noTone(BUZZER);
	}
	}
	void loop()
	{
	for (pin = 0; pin < 5; pin++) {
	if (digitalRead(BUTTON) == LOW &&
	buttonPressed == false) {
	buttonPressed = true;
	mode = !mode;
	pin = 0;
	if (mode == false) {
	tone(BUZZER, NOTE_C5, 100);
	delay(100);
	tone(BUZZER, NOTE_G5, 100);
	delay(100);
	noTone(BUZZER);
	}
	else if (mode == true) {
	tone(BUZZER, NOTE_G5, 100);
	delay(100);
	tone(BUZZER, NOTE_C5, 100);
	delay(100);
	noTone(BUZZER);
	}
	}
	if (mode == false) {
	ledArrayHigh = 13 - pin;
	ledArrayLow = 7 - pin;
	}
	else if (mode == true) {
	ledArrayHigh = 9 + pin;
	ledArrayLow = 3 + pin;
	}
	digitalWrite(ledArrayHigh, HIGH);
	digitalWrite(ledArrayLow, HIGH);
	delay(100);
	digitalWrite(ledArrayHigh, LOW);
	digitalWrite(ledArrayLow, LOW);
	if (pin == 4) delay(100);
	}
	if (buttonPressed == true) {
	buttonPressed = false;
	}
	} 更簡單的音樂程式碼:

#define Do 523

#define Re 587

#define Mi 659

#define Fa 698

#define So 784

int melody[]={Do,Re,Mi,Do,Do,Re,Mi,Fa,So};

void setup(){

    delay(1000);

    pinMode(8,OUTPUT);

    for(int i=0;i<11;i++){

    tone(8,melody[i],100);

    delay(130);

  }

}

void loop(){

    

}
