distanceCm= duration*0.034/2;
distanceInch = duration * 0.01330 / 2;
lcd.setCursor(0,0); 
lcd.print("Distance: "); // Prints string "Distance" on the LCD
lcd.print(distanceCm); // Prints the distance value from the sensor
lcd.print("   cm");

lcd.setCursor(0,1);
lcd.print("Distance: ");
lcd.print(distanceInch);
lcd.print(" inch");
