Good, I understand the goals. Here are some possible high level approaches:
Bluetooth between Android app/phone and arduino. Plus side cheap and easy to do. Negative side must be close to each other to pair (15 meters open air).
Wireless between Android app/phone and arduino. Plus side still not too much cost and support easy to find. Range better but still within 25 meters. Negative would be setup phone each time you wish to use app(small pain).
GSM/CDMA between Android app/phone and arduino. Certainly range not a problem. But cost for using would need subscription to wireless carrier and would be like calling a number. Ugh in my mind.
Other???
So you see some choices to make before going into the details. I suggest google each and weigh pros/cons of each. I just touched on the high level details.
Thanks for responding Clem. Maybe a better understanding of what I am trying to accomplish will suffice. My project deals with reading voltage from a 9v Battery into an Android App. As you can see i'm a novice. All I have heard is that the Arduino is the best solution for a novice getting into programmable electronics. Therefore, if anyone can actually help me with the parts I need, (and maybe some instructions) little by little, I will figure out how to make it work. Of course, with the resources available on element 14.
Truthfully, I am even uncertain about what you mean by a board solution.
