Example program (UNO development board):

volatile int limitswitchPin;
volatile int led;

boolean mixly_digitalRead(uint8_t pin) {
  pinMode(pin, INPUT);
  boolean _return =  digitalRead(pin);
  pinMode(pin, OUTPUT);
  return _return;
}

void setup(){
  limitswitchPin = 4;
  led = 9;
  Serial.begin(9600);
}

void loop(){
  //碰撞开关接uno开发板D4引脚；LED灯模块接D9引脚

  if (mixly_digitalRead(limitswitchPin) == LOW) {
    Serial.println("触发开关，点亮led1秒");
    pinMode(led, OUTPUT);
    digitalWrite(led,HIGH);
    delay(1000);

  } else {
    Serial.println("没有触发开关，熄灭led");
    pinMode(led, OUTPUT);
    digitalWrite(led,LOW);

  }
  delay(500);
