Automated mouse trap with ardiuno

 In this project I tried to build a plexiglas box with laser cut. I have used arduino, servo motor to release the door and ultrasonic sensor to detect the mouse inside the box.

If I had to it again, I would choose stronger servo motor, this specific one, was making some kind of noise, probably its because it was not strong enough to hold the door stretched with elastic.

After a while the servo turned itself without detecting anything. I am thinking that might be either the servo motor is weak or the plexiglas was reflecting to the sensor thereby creating the signal to servo.

Overall, I am very happy with the result and i really enjoyed it!

if you have a laser cutter at home or in a workshop where you can access to a laser cutter, you can contact me via the contact form on the right navigation bar so I can send you the project file by email.

Items used on the project.

1. Arduino Uno
2. Ultrasonic sensors
3. Servo motor
4. Drawing

Wirering diagram

Arduino Code:

#include <Servo.h>

Servo servo;

int const trig = 3;

int const echo = 2;

void setup()

{

pinMode(trig, OUTPUT); 

pinMode(echo, INPUT);

servo.attach(4);

}

void loop()

{       

  int duration, distance;

  digitalWrite(trig, HIGH); 

  delay(1);

  digitalWrite(trig, LOW);

  duration = pulseIn(echo, HIGH);

  distance = (duration/2) / 29.1;

  

  if (distance <= 8 && distance >= 0)

    {

    servo.write(50);

    delay(3000);

    }

    else {

      servo.write(160);

      }

      delay(30);

      }
