NHD-0420D3Z-NSW-BBW-V3 w/Arduino Atmega 2560

So lets start this off with.. this is a very novice question but.. I do NOT do code very often if at all to be honest. Are there any example codes showing exactly how to set this display up?

I am looking to use this Arduino to take readings from a speed sensor and be able to display the speed onto the LCD.

Anything to point me in the right direct would be greatly appreicated.

Thanks guys,
Mo
