+  LiquidCrystal Library - Blink
+ 
+ Demonstrates the use 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 "Hello World!" to the LCD and makes the 
+ cursor block blink.
+ 
+ The circuit:
+ * LCD RS pin to digital pin 12
+ * 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

+   * wiper to LCD VO pin (pin 3)
