Ps: this is so we don't bust our limit switch

we use a pid (proportional input device?) for this. It speeds itself up the farther it is from its destination. However, you'll need an encoder or something for this.

If you can't find code for a pid loop on Kevin Watson's site, tell me and I'll see what I can do for you.
