STEM教育 · 用Boson&Arduino实现跳一跳外挂装置

最近微信推出的小游戏“跳一跳”

刷爆了朋友圈

如何才能刷到2999分？

光靠手指是不行的，还是要外援！

接下来我们来教大家用Boson模块+Arduino主控板制作简单的外挂装置~

！用玩游戏的方式学编程！

先上效果图

材料清单：

尺子，按钮模块，角度传感器模块，舵机，导电胶布，棉签，Arduino主控板+扩展板，导电线

硬件制作：

1. 将角度传感器连到A0，黄色按钮模块连到数字2号口，舵机连接到数字9号口（PMW）

2. 将棉签裹上一层导电布，然后将导电布一段接上5V导电线，（可直接连接至扩展板），即可模拟手指触摸屏幕~

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

  pinMode(ledPin, OUTPUT);
  Serial.begin(9600);
  myservo.attach(9);
  myservo.write(0);
  delay(500);
}

void loop() {
  // put your main code here, to run repeatedly:
  val = analogRead(A0);
  val = (val+1)*0.02;
  Serial.println(val);
  buttonState = digitalRead(buttonPin);
  //compare the buttonState to its previous state
  if (buttonState != lastButtonState){
//if the state has changed, increment the counter
if (buttonState == HIGH){
   buttonPushCounter++;
   play();
   Serial.println("on");
   Serial.print("number of button pushes: ");
   Serial.println(buttonPushCounter);
}else{
   //if the current state is LOW then the button
   //wend from on to off:
   Serial.println("off");
}
//dalay a little bit to avoid bouncing
delay(50);
  }
  lastButtonState = buttonState;
