  LCD5110_Basic.h - Arduino library support for Nokia 5110 compatible LCDs
  Copyright (C)2011 Henning Karlsen. All right reserved
  
  Basic functionality of this library are based on the demo-code provided by
  ITead studio. You can find the latest version of the library at
  http://www.henningkarlsen.com/electronics

  This library has been made to make it easy to use the basic functions of
  the Nokia 5110 LCD module on an Arduino.

  If you make any modifications or improvements to the code, I would appreciate
  that you share the code with me so that I might include it in the next release.
