一樣 但更簡單的電路

void setup()

{

  Serial.begin(9600);

  pinMode(2, INPUT_PULLUP);

  pinMode(13, OUTPUT); 

}

void loop()

{

  int sensorVal = digitalRead(2);

  Serial.println(sensorVal);

  if (sensorVal == HIGH)

  {

    digitalWrite(13, LOW);

  } 

  else 

  {

    digitalWrite(13, HIGH);

  }

}
