相应代码：

volatile boolean b1;
volatile boolean b2;
volatile int click;
volatile boolean lastState;
volatile boolean toggle;

void setup(){
  pinMode(13, OUTPUT);
  pinMode(8, INPUT);
  digitalWrite(13,HIGH);
  pinMode(7, INPUT_PULLUP);
  lastState = digitalRead(8);
  Serial.begin(9600);
  lastState = LOW;
  toggle = LOW;
  click = 0;
  b1 = 0;
  b2 = 0;
}

void loop(){
  Serial.println(digitalRead(7));
  b1 = digitalRead(7);
  if (b1 != lastState) {
    delay(20);
    b2 = digitalRead(7);
    if (b2 == b1) {
      lastState = b1;
      click = click + 1;

    }

  }
  if (click == 2) {
    click = 0;
    toggle = !toggle;
    digitalWrite(13,toggle);

  }

}
