      2   LiquidCrystal Library - Hello World
      3 
      4  Demonstrates the use a 16x2 LCD display.  The LiquidCrystal
      5  library works with all LCD displays that are compatible with the
      6  Hitachi HD44780 driver. There are many of them out there, and you
      7  can usually tell them by the 16-pin interface.
      8 
      9  This sketch prints "Hello World!" to the LCD
     10  and shows the time.
     11 
     12   The circuit:
     13  * LCD RS pin to digital pin 12
     14  * LCD Enable pin to digital pin 11
     15  * LCD D4 pin to digital pin 5
     16  * LCD D5 pin to digital pin 4
     17  * LCD D6 pin to digital pin 3
     18  * LCD D7 pin to digital pin 2
     19  * LCD R/W pin to ground
     20  * LCD VSS pin to ground
     21  * LCD VCC pin to 5V
     22  * 10K resistor:
     23  * ends to +5V and ground
     24  * wiper to LCD VO pin (pin 3)
