+ LiquidCrystal Library - Custom Characters
+
+ Demonstrates how to add custom characters on an 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 prints "I <heart> Arduino!" and a little dancing man
+ to the LCD.
+
+ 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
+ * LCD R/W pin to ground
+ * 10K potentiometer:
+ * ends to +5V and ground
+ * wiper to LCD VO pin (pin 3)
+ * 10K poterntiometer on pin A0
