/* -----------------------------------------------------------------------------------
 * Adaption of the LCD4Bit library shipped with Arduino 22
 * for use with 74C595 shift register adapter board found on:
 * http://www.stephenhobley.com
 
 * Code adaption by Steve Hobley - February 2011

 /*---Shift Register 74HC595---
 * [SR Pin 14 (DS)]    to Arduino pin - Yellow wire [datapin]
 * [SR Pin 12 (ST_CP)] to Arduino pin - Green wire  [latchpin]
 * [SR Pin 11 (SH_CP)] to Arduino pin - White wire  [clockpin]
 * Black wire to Ground
 * Red wire to +5v
