Automatic Gate open and close Using ultrasonic sensor

Things used in this project

Hardware components

Arduino UNO

SG90 Micro-servo motor

Ultrasonic Sensor - HC-SR04 (Generic)

Story

Hello nerds, we are back with another new post. In this article, we will show you that how you can make your own automatic gate open and close system using Arduino UNO and HC SR04 ultrasonic sensors. These automatic doors can be seen in offices, hotels, etc. A programmed entryway will work best where people can not enter or work. On the off chance that the distance is under 60 cm (optimal distance), the door will open. Make the circuit as per the given outline and afterward transfer the code.

Description

the ultrasonic sensor will be used there to sense the incoming vehicles.
when the vehicle will going through the sensor, it will sense and transfer the data to the arduino
It will calculate the distance between vehicle and sensor.

Then the entryway will open and after a hole of a couple of moments, it will close consequently.

We attach a servo motor to the gate.
The motor will move 180 degrees and come back to its initial position once again.

Components Required

Arduino UNO
HC SR04 ultrasonic sensor
Servo motor
Jumper wires
USB cable for uploading the code
breadboard

this is one of the best project made by me and all the detail has been given here and if you want more information like how we made the PCB from PCBWAY and the other detail you can visit the reference website techatronic.com

Code

Code

#include <Servo.h>
Servo servoMain; // Define our Servo
int trigpin = 10;
int echopin = 11;
int distance;
float duration;
float cm;

void setup()
{
   servoMain.attach(9); // servo on digital pin 10
    pinMode(trigpin, OUTPUT);
    pinMode(echopin, INPUT);
}

void loop()
{ 
  digitalWrite(trigpin, LOW);
  delay(2);  
  digitalWrite(trigpin, HIGH);
  delayMicroseconds(10);  
  digitalWrite(trigpin, LOW);  
  duration = pulseIn(echopin, HIGH);  
  cm = (duration/58.82);
  distance = cm;
  
  if(distance<60)
  {
    servoMain.write(180);  // Turn Servo back to center position (90 degrees)
   delay(3000); 
  }
   else{
     servoMain.write(0);
     delay(50);
   }
   
}
