ULTRA SONIC SENSOR TO ARDUINO

Here you will get the information how to connect the ultra sonic sensor to the arduino platform

for pin discription see below the code.

/*

  distance sensor]
 VCC to arduino 5v GND to arduino GND
 Echo to Arduino pin 6 Trig to Arduino pin 7

#define trigPin 5
#define echoPin 6

void setup() {
  Serial.begin (9600);
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);
}

void loop() {
  long duration, distance;
  digitalWrite(trigPin, LOW);  // Added this line
  delayMicroseconds(2); // Added this line

  digitalWrite(trigPin, HIGH);
//  delayMicroseconds(1000); - Removed this line
  delayMicroseconds(10); // Added this line
  digitalWrite(trigPin, LOW);
  duration = pulseIn(echoPin, HIGH);
  distance = (duration/2) / 29.1;
  if (distance >= 200 || distance <= 0){
    Serial.println("Out of range");
  }
  else {
    Serial.print(distance);
    Serial.println(" cm");
  }
  delay(500);
}

Connect the ultra sonic sensor...and done the work
