2  LiquidCrystal Library - Hello World
3
4 Demonstrates the use   a 16x2 LCD display.  The LiquidCrystal
5 library works with all LCD displays that   are compatible with the
6 Hitachi HD44780 driver. There are many of them out there,   and you
7 can usually tell them by the 16-pin interface.

9 This sketch prints   "ROBO-CREATORS" to the LCD
10 and shows the time.

12  The circuit:
13 *   LCD RS pin to digital pin 12
14 * LCD Enable pin to digital pin 11
15 * LCD D4   pin to digital pin 5
16 * LCD D5 pin to digital pin 4
17 * LCD D6 pin to digital   pin 3
18 * LCD D7 pin to digital pin 2
19 * LCD R/W pin to ground
20 * LCD VSS   pin to ground
21 * LCD VCC pin to 5V
22 * 10K resistor:
23 * ends to +5V and   ground
24 * wiper to LCD VO pin (pin 3)
