LCD display library(LiquidCrystal.h) = http://bit.ly/2VeF5xt


Code :-

 #include <LiquidCrystal.h>//Include LCD library

 LiquidCrystal lcd(9,8, 4, 3, 2, 1);// initialize the library with the numbers of the interface pins

 void setup() {
  lcd.begin(16, 2);
  lcd.print("Mr.Arduino");// Print a message to the LCD.
}

 void loop() {
  lcd.setCursor(0, 1);
  lcd.print("  LCD Tutorial");//Print a message to second line of LCD

}
