/* * * copyleft 2011 snootlab * free software, have fun ! * based on arduino LiquidCrystal Library - TextDirection 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 how to use leftToRight() and rightToLeft() to move the cursor. Library originally added 18 Apr 2008 by David A.
