library by providing the nuber of pins to it
LiquidCrystal lcd(2,
3, 8, 9, 10, 11);
void setup() {
lcd.begin(16,2);
// set cursor
position to start of first line on the LCD
lcd.setCursor(0,0);
//text to print
lcd.print("16x2
LCD Interfac");
// set cusor position
to start of next line
lcd.setCursor(2,1);
lcd.print("by
Engr.Habib");
}
