so from discussion on this node, I was able to come up with ideas, thanks guys!
I don't have an image to describe what I want to do with the sensor on my skates because A: I suck at drawing, and B: I suck at drawing on my computer.
At first I wasn't too concerned about having an "exact" distance traveled, just some number that if I saw it go higher with each skate session, that would make me happy, but of course you guys got my brain juice goin'.
