Description:-

A lot of intrusion activities/security threats in the army area are seen nowadays. This gave me an idea to build something that helps the army and worked on it. I implemented this project by thinking about the basic idea of my project and used the materials required to detect movements and used Arduino UNO to send commands to Servo motor and Ultrasonic Sensor. Not only in the army but it can be implemented anywhere where security arrangements are required.

Project Used Hardware

Arduino UNO, Servo Motor, Ultrasonic Sensor, Buzzer, LED Bulb, Arduino Cable, 9V Battery, 3V Battery, SPST (Single Pole Single Throw) Switch

Project Used Software

Arduino IDE

Project Hardware Software Selection

Hardware Selection: Arduino UNO was used to send commands to the other components. Servo Motor was used to lift up the road. Buzzer was used as a security alarm. Ultrasonic Sensor was used to detect suspicious movement. An LED Bulb was used to show the prohibited zone. Arduino Cable was used to give power to Arduino. A 9V Battery was used to give power to the buzzer. A 3V Battery was used to give power to the LED. SPST (Single Pole Single Throw) Switch was used to control the power supply. Software Selection: Arduino IDE was used to program Arduino UNO and transfer the program instructions to Arduino UNO.

Circuit Diagram

The Vcc pin of the ultrasonic sensor is connected to the 5V power pin of the Arduino UNO. The trigger pin of the ultrasonic sensor is connected to Digital pin number 5 of the Arduino UNO. The echo pin of the ultrasonic sensor is connected to Digital pin number 6 of the Arduino UNO. The ground pin of the ultrasonic sensor is connected to the Digital Ground pin of the Arduino UNO. The negative terminal of the servo motor is connected to the Ground pin of the Arduino UNO. The positive terminal of the servo motor is connected to the 3.3V power pin of the Arduino UNO. The signal pin is connected to the Digital pin number 7 of the Arduino UNO.

duration = pulseIn(echoPin, HIGH);

dist = (duration/2) / 29.1;    //obtain distance

}

void loop() {

  for (int i=0;i<=2;i++) {   //average distance

    measure();              

   aver[i]=dist;           

    delay(10);              //delay between measurements

  }

 dist=(aver[0]+aver[1]+aver[2])/3;   

if ( dist<15 ) {

//Change distance as per your need

 servo.attach(servoPin);

  delay(1);

 servo.write(0); 

 delay(3000);      

 servo.write(1500);   

 delay(1000);

 servo.detach();     

}

Serial.print(dist);
