First, thanks for having this forum. Second, I'm pretty ignorant so please forgive any stupid questions. I'd like to add a display to the project I am working on (using an Arduino Mega). I'm thinking about the 20x4 lcd with backpack. As I understand it, the backpack requires two pins, would any two analog/digital pins work? Will I run into any issues using it and the Ethernet Shield? Also, I couldn't find a link to the library for the backpack. Could you kindly point me to it?
