I'm currently working on a project that needs to use the MIT Handy Board, but also needs to use two of the the Devantech TPA81 Thermal Arrays (as seen at http://www.robot-electronics.co.uk/htm/tpa81tech.htm
). Basically, it'll be used to detect if a person is present through the heat of their body... However, since the Handy Board doesn't have enough I2C ports, we need to use the Arduino Uno to receive that information and report it back to the Handy Board (where the bulk of our programming will be). We don't know much about interfacing the two, though....
Can anyone offer some tips on how to get these boards to work together?
