                     codings for ultrasonic sensor

#define trig 5
#define echo 6
void setup() {
  Serial.begin(9600);
  pinMode(trig,OUTPUT);
  pinMode(echo,INPUT);
  pinMode(13,OUTPUT);
}

void loop() {
  long duration , distance;
  
  digitalWrite(trig,LOW);
  delay(2);
  digitalWrite(trig,HIGH);
  delay(2);
  digitalWrite(trig,LOW);
  
  duration= pulseIn(echo,HIGH);
  distance=(duration/2)/29.1;

  if(distance <= 10)
  {
    digitalWrite(13,HIGH);
  }
  else
  {
    digitalWrite(13,LOW);
  }
  
 delay(1000);
