  LiquidCrystalFast Library - Blink
 
 Demonstrates the use a 16x2 LCD display.  The LiquidCrystalFast
 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 makes the 
 cursor block blink.
 
 The circuit:
 * LCD RS pin to digital pin 12
 * LCD WR pin to digital pin 10
 * LCD Enable pin to digital pin 11
 * LCD D4 pin to digital pin 5
 * LCD D5 pin to digital pin 4
 * LCD D6 pin to digital pin 3
 * LCD D7 pin to digital pin 2
 * 10K resistor:
   * ends to +5V and ground
   * wiper to LCD VO pin (pin 3)
