喬的沒睡飽日常 Week12

按第八個按鈕會唱Mi

int Do = 523;
int Re = 587;
int Mi = 659;
void setup() {
  pinMode(8,OUTPUT); //8:Buzzer第八個按鈕
  pinMode(2,INPUT_PULLUP);//2:你的MakerUNO的按鈕

}

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

按數次按鈕唱歌

int Do = 523;
int Re = 587;
int Mi = 659;
int Fa = 698;
int So = 784;
int song[10]={Mi,Do,Re,Mi,Do,Mi,So,Fa,Mi,Re};//10個音符
int now=0;
bool UP = true;//判斷是不是true
void setup() {
  pinMode(8,OUTPUT); //8:Buzzer第八個按鈕
  pinMode(2,INPUT_PULLUP);//2:你的MakerUNO的按鈕

}

void loop() {
  if(UP && digitalRead(2)==LOW){
    tone(8,song[now],1000);
    UP=false;
    //now++;
    now = (now+1)%9; //避免song[now]超過而當機
  }
  else{
    //noTone(8);
    UP = true;
  }
  delay(100);
}
