開啟範例檔:

測試: 開啟序列阜監控室窗測試

會發現，按住按鈕開關視窗會顯示"0"，放開會顯示"1"

void loop() {

  //read the pushbutton value into a variable
  int sensorVal = digitalRead(2);
  //print out the value of the pushbutton
  Serial.println(sensorVal);

  // Keep in mind the pullup means the pushbutton's
  // logic is inverted. It goes HIGH when it's open,
  // and LOW when it's pressed. Turn on pin 13 when the
  // button's pressed, and off when it's not:
  if (sensorVal == HIGH) {
    digitalWrite(13, LOW);
  } else {
    digitalWrite(13, HIGH);
  }
}

Processing與Arduino做結合

開啟Processing的Arduino控制範例檔案

改Processing的 portName 跟 ARDUINO的序列阜一樣

再把Processing的Arduino Code for loop() copy 到 Arduino 裡面 ，並且把 switchPin

改成"2" (因為pinMode(2, INPUT_PULLUP);是2)
