I am new to both the arduino and the arduinix.  I assembled the arduinix and all appears to be working fine.  I want to extend the model and introduce other hardware (e.g. a motion sensor to turn on the display).  I am of limited experience with the arduino, but I am smart enough to know that I would need to attach it to the arduino to be able to code to it, my question is what pins are available to use?  It looks like the analog pins are optionally connected to the arduinix; I connected those when I assembled the board.  This was not clear to me when I did the assembly so I added the pins and completed the connections.

If this is optional, what was accomplished by connecting these to the arduinix?  If I remove that connector can I then use those pins for other purposes?  Any insight here would be appreciated.

Those analog pins are available, they have been used in code as buttons for set time, but they don't have to be.

You can solder a set of wires to the top of the headers above the board if you need to.

On an Uno, the ArduiNix uses digital pins 2 through 13. Everything else is available to you.

For my build, instead of the downward-facing male headers that are included, I used stackable pass-through headers. This gave me access to all of the Arduino pins, which was great for adding other inputs, but also for debugging (and I needed a lot of that).
