#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);   
// Creates an LCD object. Parameters: (rs, enable, d4, d5, d6, d7)

void setup() 
{
  // set up the columns and rows:
  lcd.begin(16, 2);
  // Clears the LCD screen
  lcd.clear();
}
void loop() 
{
  lcd.setCursor(3, 0);
      // set the cursor to column 3, line 0
  lcd.print("Hello world!");
     // Print a message to the LCD.
   lcd.setCursor(3, 1);
     // set the cursor to column 3, line 1
  lcd.print("Hello world!");
    // Print a message to the LCD
