  LiquidCrystal Library - setCursor
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.

 This sketch prints to all the positions of the LCD using the
10
 setCursor(0 method:

  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
 * 10K resistor:
21
 * ends to +5V and ground
22
 * wiper to LCD VO pin (pin 3)
