LiquidCrystal Library - scrollDisplayLeft() and scrollDisplayRight()
Demonstrates the use of a 16x2 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 "Arduino Sketch" to the LCD and uses the 
scrollDisplayLeft() and scrollDisplayRight() methods to scroll 
the text.
