  const int rs = 7, en = 6, d4 = 5, d5 = 4, d6 = 3, d7 = 2;

  const int triggerPin = 9, echoPin = 8;

  LiquidCrystal_I2C lcd(0x27, 16, 2);

  // Maksimum pembacaan sensor (400cm) //

  const int measureLimit = 200;

  int duration = 0, distance = 0;

void setup()

{

   Serial.begin(9600);

  pinMode(triggerPin, OUTPUT);

  pinMode(echoPin, INPUT);

  lcd.begin();

  lcd.setCursor(6, 0);

  lcd.println("Blog:");

  lcd.setCursor(0, 1);

  lcd.print("Mahirelektro.com");

  delay(2000);

  lcd.clear();

  lcd.setCursor(0, 0);

  lcd.print("Jarak = ");

}

void loop()

{

  lcd.setCursor(8, 0);

  readSensor();

  lcd.print(distance);

  lcd.println(" cm       ");

  Serial.print("jarak =");

  Serial.print(distance);

  Serial.print(" cm        ");

 

}

void readSensor()

{

  digitalWrite(triggerPin, LOW);

  delayMicroseconds(2);

  digitalWrite(triggerPin, HIGH);

  delayMicroseconds(10);

  digitalWrite(triggerPin, LOW);

  duration = pulseIn(echoPin, HIGH);

  distance = (duration / 2) / 29.1;

  distance = constrain(distance, 0, measureLimit);
