LiquidCrystal Library – Hello World

Demonstrates the use a 16×2 LCD display.  The LiquidCrystal
library works with all LCD displays that are compatible with the
Hitachi HD44780 driver. There are many of them out there, and you
can usually tell them by the 16-pin interface.

This sketch prints “Hello World!” to the LCD
and shows the time.

The circuit:
* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 10
* LCD D4 pin to digital pin 7
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 8
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground
* 10K resistor:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)
