Part 1 按123對應的LED發亮

int Do = 523
int Re = 587
int Mi = 659 //音符
void setup() {
  pinMode(8, OUTPUT); //8: Buzzer
  pinMode(2, INPUT_PULLUP); //2: Buttom
}

void loop() {
  if(digitalRead(2)==LOW)  tone(8,Do,1000);
  else noTone(8);
}

Part 2 小蜜蜂

int Do = 523
int Re = 587
int Mi = 659
int song[9] = {Do, Re, Mi, Do, Do, Re, Mi, Do, Mi};
int now=0;
bool UP = true;
void setup() {
  pinMode(8, OUTPUT);//8: Buzzer
  pinMode(2, INPUT_PULLUP);//2: Buttom
}

void loop() {
  if (UP && digitalRead(2) == LOW) {
    tone(8, song[now], 200);
    UP = false;
    now=(now+1)%9;
  }
  else {
    UP=true;
  }
  delay(100);
}

Part 3 按鍵發聲

void setup() {
  for (int i = 2; i <= 13; i++) {
    pinMode(i, INPUT_PULLUP);
  }
  pinMode(8, OUTPUT);
}

void loop() {
  if (digitalRead(2) == LOW) tone(8, 523, 200);
  if (digitalRead(3) == LOW) tone(8, 587, 200);
  if (digitalRead(4) == LOW) tone(8, 659, 200);
  if (digitalRead(5) == LOW) tone(8, 698, 200);
  if (digitalRead(6) == LOW) tone(8, 784, 200);
  if (digitalRead(7) == LOW) tone(8, 880, 200);
  if (digitalRead(9) == LOW) tone(8, 988, 200);
  if (digitalRead(10) == LOW) tone(8, 1047, 200);
