How Make Mouse Trap at your home

Circuit:

Arduino Programming:

#include <Servo.h>

int ir_sensor = A0;

Servo myservo;

int pos = 0;

void setup() {

  myservo.attach(9);

  myservo.write(0);

}

void loop() {

  int sensor_value = analogRead(ir_sensor); //read the sensor value

  int distance_cm = pow(3027.4/sensor_value, 1.2134); //convert readings to distance(cm)

  if (distance_cm < 10) {

  myservo.write(180);

  delay(10);

  }

  else

    delay(1000);

    myservo.write(0);

    delay(100);

}
