// include the library code:

// initialize the library with the numbers of the interface pins
 LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
 // set up the LCD's number of columns and rows:
 // This particular 16x1 LCD is treated as an 8x2.  8 Characters by 2 rows.
 lcd.begin(8, 2);
 }

void loop() {
 lcd.print("hello, w");
 lcd.setCursor(0, 1);
