LCD and Serial Communication

I have programmed all basic minor and major chords into the Arduino. My next is goal is to be able to select which chord you would like to play. This will be down with some push buttons and an LCD. The LCD Library that the Arduino uses is great, but it is use a lot of of the arduino's pins. With a shift register we can go from using 6 pins to 3. Anyways, I just wanted to share this Arduino Library I found and plan on using in my code. It writes to an LCD with a 595 chip (serial in parallel out). He does a great job documenting his work so it is really easy to follow.  Controlling and LCD with a Shift Register.
