-  LiquidCrystal Library - display() and noDisplay()
- 
- 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 uses the 
- display() and noDisplay() functions to turn on and off
- the display.
- 
- 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
- * 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)
