  LiquidCrystal Library - Hello Sparky
 
 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 shows the time.
 
  The circuit:
 * LCD RS pin to digital pin D0
 * LCD EN pin to digital pin D1
 * LCD D4 pin to digital pin D2
 * LCD D5 pin to digital pin D3
 * LCD D6 pin to digital pin D4
 * LCD D7 pin to digital pin D5
 * 10K resistor:
 * ends to +5V and ground
 * wiper to LCD VO pin (pin 3)
 * connect R/W (pin 5) to ground
