Distance Measuring Device without LCD screen, jumper wire, breadBoard

DISTANCE MEASURING DEVICE

(Arduino based)

Hello! I am Shlok Jain. I have made here a distance measuring device with only ultrasonic sensor and arduino uno board. It's a very easy task to make this.

I have not used jumper wire or breadboard or LCD screen here.

If you have 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

1. Arduino UNO board

      2. Ultrasonic sensor

STEPS TO MAKE IT

STEP 1: Connect ultrasonic sensor with arduino uno board.

as shown in figure. Leave first three pins and apply sensor directly to board.

STEP 2: Connect arduino board with computer with cable that comes with arduino uno

Download Arduino IDE and paste given code in that application.

Now upload the given code by clicking the arrow symbol at upper left of computer screen.

int trig=12;
int echo=13;

void setup()
{
  pinMode(trig,OUTPUT);
  pinMode(echo,INPUT);
  pinMode(11,OUTPUT);
  digitalWrite(11,HIGH);
  Serial.begin(9600);
}

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;

  Serial.println("distance:");
  Serial.print(dist);
  Serial.println("cm");

  delay(3000);

}

STEP 3: Now click on Tools on 

       Now open Serial Monitor.

Now a new window will open 

First time it will show wrong reading then correct reading.

So we are done !!!!!

Thank you for watching
