Distsance finder by using ultrasonic sensor with Arduino

Distsance finder by using ultrasonic sensor with Arduino

Apparatus required:

1x Ultrasonic sensor

1x Arduino board


1x DC supply


4x Male to female jumper connecting wire

Construction:

Step 1:  Upload the program given below in to Arduino board 

Step 2:  Connect the Arduino and Ultrasonic sensor in to the pins  trigPin-9, echoPin-10

Step 3: Now click serial monitor in the Arduino software 

Step 4:  Move your sensor and find distance approx,

Step 5: Follow us and subscribe our YouTube channel

Program:

#define trigPin 9

#define echoPin 10

void setup() {

  Serial.begin (9600);

  pinMode(trigPin, OUTPUT);

  pinMode(echoPin, INPUT);

}

void loop() {

  long duration, distance;

  digitalWrite(trigPin, LOW);

  delayMicroseconds(2);

  digitalWrite(trigPin, HIGH);

  delayMicroseconds(10);

  digitalWrite(trigPin, LOW);

  duration = pulseIn(echoPin, HIGH);

  distance = (duration/2) / 29.1;

  if (distance >= 400 || distance <= 2){

    Serial.println("Out of range");

  }

  else {

    Serial.print(distance);

    Serial.println(" cm");

  }

  delay(500);

}
