+  LiquidCrystal Library - Autoscroll
+

+ library works with all LCD displays that are compatible with the

+
+ This sketch demonstrates the use of the autoscroll()
+ and noAutoscroll() functions to make new text scroll or not.

+ 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

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

+sentence=Allows communication with alphanumerical liquid crystal displays (LCDs). For all Arduino boards.
+paragraph=This library allows an Arduino board to control LiquidCrystal displays (LCDs) based on the Hitachi HD44780 (or a compatible) chipset, which is found on most text-based LCDs. The library works with in either 4 or 8 bit mode (i.e. using 4 or 8 data lines in addition to the rs, enable, and, optionally, the rw control lines).
