+ LiquidCrystal Library - Increment/Decrement
+
+ 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 demonstrates the use of the shiftIncrement()
+ and shifDecrement() functions.
+
+ 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)
