Ultrasonic Sensor Arduino

In this Project, we will see about how to interface Ultrasonic Sensor with Arduino .

Circuit Diagram:

Arduino Code:

#define echoPin 13
#define trigPin 12

long duration, distance;

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

void loop() {
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  duration = pulseIn(echoPin, HIGH);
  distance = duration / 58.2;
  Serial.println(distance);
  delay(100);
}

  distance = duration / 58.2;
  Serial.println(distance);
  if (distance < 10) {
    digitalWrite(red, HIGH);
    digitalWrite(green, LOW);
  }
  else {
    digitalWrite(red, LOW);
    digitalWrite(green, HIGH);
  }
  delay(100);
}
