Week13

改成2,因為MakerUNO的按鈕在pin2

int switchPin = 4;                       // Switch connected to pin 4

void setup() {

  //pinMode(switchPin, INPUT);             // Set pin 0 as an input

  pinMode(2,INPUT_PULLUP);

  Serial.begin(9600);                    // Start serial communication at 9600 bps

}

void loop() {

  if (digitalRead(2) == HIGH) {  // If switch is ON,

    Serial.write(1);               // send 1 to Processing

  } else {                               // If the switch is not ON,

    Serial.write(0);               // send 0 to Processing

  }

  delay(100);                            // Wait 100 milliseconds

}
