Ultrasonic Sensor and LCD Display code help needed !!

Projects General Guidance
15

Built one a few days ago, this works for me:

#include <LiquidCrystal.h>
#define trigPin 8; //Define the Trigger pin of the Ultrasonic
#define echoPin 9; //Define the Echo pin of the Ultrasonic

LiquidCrystal lcd(12, 11, 5, 4, 3, 2); //Define LCD pins

void setup() {
  lcd.begin(16, 2); //Setup LCD
  pinMode(trigPin, OUTPUT); //Setup Trigger and Echo
  pinMode(echoPin, INPUT);
}

void loop() {
  int duration, distance;
  digitalWrite(trigPin, HIGH); //Write High for 1ms
  delayMicroseconds(1000);
  digitalWrite(trigPin, LOW);
  duration = pulseIn(echoPin, HIGH); //Time pulse in
  distance = (duration/2) / 29.1; //Convert time to Cm
  if (distance >= 200 || distance <= 0){
    lcd.clear();
    lcd.setCursor(2,0);
    lcd.print("Out of Range");
  }
  else {
    lcd.clear();
    lcd.setCursor(2,0); //Print to screen
    lcd.print(distance);
    lcd.setCursor(5,0);
    lcd.print(" Cm");
  }
  delay(300);
}

Hope this helps,
