This project uses a 4 bit data bus to communicate with the LCD.
The download and installation of the library (LCD4BitLibrary) can be found here. Ensure the library are place in this location of your development path arduino-0012\hardware\libraries\LCD4Bit
The use of 4 bit reduces the number of IO lines required from the Arduino. The RW line on the LCD is tied to ground, making it write only. This makes a total of only 6 IO lines required. 4 Data, RS and E. Discussion on this project in forum.
