程式碼:

void setup(){

  //start serial connection

  Serial.begin(9600);

  //configure pin2 as an input and enable the internal pull-up resistor

  pinMode(2, INPUT_PULLUP);

  pinMode(3, INPUT_PULLUP);

  pinMode(13, OUTPUT); 

}

void loop(){

  //read the pushbutton value into a variable

  int sensorVal = digitalRead(2);

  int sensorVal3 = digitalRead(3);

  if (sensorVal == LOW)Serial.print('0');

  if (sensorVal3 == LOW)Serial.print('1');

}

片段程式碼:

import processing.serial.*;

Serial myPort;

int val; 

void setup() {

  size(640, 480, P3D);

  myPort = new Serial(this, "COM3", 9600);

  rectMode(CENTER);

}

void draw() {

  while (myPort.available ()>0) {

    val=myPort.read();

    if (val==48) {

      carX+=cos(carDir+carWheel);

      carY+=sin(carDir+carWheel);

      carDir+=carWheel/50;

    } else if (val==49) {

      carX-=cos(carDir+carWheel);

      carY-=sin(carDir+carWheel);

      carDir-=carWheel/50;

    }

  }

  println(val);

  background(100);

  drawCar();

  rect(0+187/2, 0+89/2, 187, 89);

  rect(450+187/2, 0+89/2, 187, 89);

}
