RGB LCD controlled by Arduino using 3 wire shift register.

This is a simple breadboard and shield design of a 3 wire shift register and an RGB LCD for the Arduino UNO. The purpose is to save pins on the Arduino.

I used the 74HC595 with the three-wire method schematic from http://code.google.com/p/arduinoshiftreglcd/

The red, blue and green LED are controlled by the PWM pins, 6, 5 and 3, respectively.
