I am thinking of working on project with my teenage son and some of his friends. The want to put something in a toy car and then write an android (and maybe eventually iphone) app that tracks on the screen where the toy car is being driven. We are wondering what device/technology should we put in the toy car (rfid, bluetooth, wifi or ?). The toy car is about twice as big as a hotwheel car so we don't quite have room for a full size arduino, but maybe something like a trinket? Or if we go the rfid route, would that give us enough accuracy? Or do you have any other ideas?
Thanks
