Anyhow, just wanted to inform that I've put in my 1st sparkfun order which consists of an Uno, resistor pack, protoshield with miniboard (so I can mount the whole uno board on the leg for testing)...and the tilt switch. I suppose I'll start it off simple, see how the tilt switch solution works, if not, place another sparkfun order for other sensors (force, flex, etc).... Wish me luck!
