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 - scrollDisplayLeft() and scrollDisplayRight() methods to scroll - the text. - - 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 - * 10K resistor: - * ends to +5V and ground - * wiper to LCD VO pin (pin 3) - - Library originally added 18 Apr 2008 - by David A.
