Joystick滑動-變換音頻:

 void setup() {

  pinMode(8,OUTPUT);

}

void loop() {

  int now =analogRead(A0); 0~511 Hz

  tone(8,now);

}

Joystick滑動-燈光閃爍程度

void setup() {

  // put your setup code here, to run once:

  for(int i=2;i<=13;i++){

    pinMode(i,OUTPUT);

  }

}

void loop() {

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

  int now =analogRead(A0);

  int level =now/(512/13);

  for(int i=2;i<=13;i++){

    if(i<level)digitalWrite(i,HIGH);

    else digitalWrite(i,LOW);

  }

}
