Automatic Barrier Opening System using arduino

Automatic Barrier Opening system

Hello! I am Shlok Jain. I have made Automatic Barrier Opening System. It's a very easy task to make this.

If you hane not viewed my youtube video then go and view it. Here it is.

Also don't forget to like, share, and subscribe my channel. 

Materials Required

• Arduino UNO
• Ultrasonic sensor
• Servo motor
• some jumper wires
• breadboard

Steps to make it

Step 1:Make connections according to given circuit diagram.

Step 2: Now download arduino IDE.

Now open application. Clear everything written on it. And paste following code there.

                    
#include<Servo.h>

int trig=2 , echo=3;
Servo servo;

void setup()
{
  servo.attach(5);
  pinMode(trig,OUTPUT);
  pinMode(echo,INPUT);
}

void loop()
{
  long samay,dist;
  digitalWrite(trig,LOW);
  delay(2);

  digitalWrite(trig,HIGH);
  delay(10);

  digitalWrite(trig,LOW);

  samay=pulseIn(echo,HIGH);
  dist= samay*0.034/2;

  if(dist<10)
  {  
    servo.write(90);
    delay(2000);
  }

  else
  { 
    servo.write(0);   
  }
}
                        
                        

Step 3:Now connect arduino UNO board with computer/laptop with cable that comes with arduino uno.

And upload code.

Step 4:Now we are done!!!!!
