Thanks for the sheet Mike. It's not nearly as detailed as I'd had hoped, and I still have hope there is a more detailed one floating around somewhere, but this is certainly better then the single sheet FIRST had.

Check out
www.klixon.com. This is the actual manufacturer of the device and has more info. There is also a document titled " Accelerometers and How They Work". It is a good tutorial and gives some clues as to use of this device. My estimate is that the two Hall Sensors giving rotational data from the BOT directional movement along with the data from the accelerometer could be used for BOT navigation. Dave Lavery mentioned PID in the kickoff presentation while he was demoing the robots. Do a search on the term or acronym PID relating it to robotics and you will find some links for connecting these sensors. I have just glanced at the software listed in the manual (has lots of nav stuff imbedded). There is a specific module named "PID.C". So take it from there. Best wishes for the season! Larry U.
