  PARTS AND MATERIALS REQUIRED!!!

  • *ARDUINO UNO (It is highly recommended to use arduino nano i doesnt had the nano so i have used uno)
  • *ULTRASONIC SENSOR
  • *A BUZZER
  • *A LED

  NOW ITS TIME TO UPLOAD THE CODE!!!!

  //Dynamic Innovator
  const int trigPin = 9;
  const int echoPin = 10;
  const int buzzer = 11;
  const int ledPin = 13;
  
  // defines variables
  long duration;
  int distance;
  int safetyDistance;
  
  
  void setup() {
  pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
  pinMode(echoPin, INPUT); // Sets the echoPin as an Input
  pinMode(buzzer, OUTPUT);
  pinMode(ledPin, OUTPUT);
  Serial.begin(9600); // Starts the serial communication
  }
  
  
  void loop() {
  // Clears the trigPin
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  
  // Sets the trigPin on HIGH state for 10 micro seconds
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
  
  // Reads the echoPin, returns the sound wave travel time in microseconds
  duration = pulseIn(echoPin, HIGH);
  
  // Calculating the distance
  distance= duration*0.034/2;
  
  safetyDistance = distance;
  if (safetyDistance <= 22
  ){ // Enter the Distance
    digitalWrite(buzzer, HIGH);
    digitalWrite(ledPin, HIGH);
  }
  else{
    digitalWrite(buzzer, LOW);
    digitalWrite(ledPin, LOW);
  }
  
  // Prints the distance on the Serial Monitor
  Serial.print("Distance: ");
  Serial.println(distance);
  }
