複習案按鍵有聲音

int Do =523;

int Re =587;

int Mi =659;

int Fa =698;

int So =784;

int song[11]={Do,Re,Mi,Do,Do,Re,Mi,Do,Mi,Fa,So};

int now=0;

bool UP=true;

void setup() {

  pinMode(8,OUTPUT);

  pinMode(2,INPUT_PULLUP);

}

int i=0;

void loop() {

  // put your main code here, to run repeatedly:

  if(UP && digitalRead(2)==LOW){ 

    tone(8, song[now],200);

    UP=false;

    now=(now+1)%11;

    

  }

  else {

  UP=true;  

  }

  delay(100);

}
