	LiquidCrystal Library - Custom Characters

	Demonstrates how to add custom characters on an 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 "I <heart> Arduino!" and a little dancing man
	to the LCD.
