My previously stated concern over the legality of having something attached as both a dashboard and controller would then still apply; not to overly discourage you.
i was thinking of using a digital potentiometer into the Driver station

i wouldn't, what i was saying was that it could send the position through the analog in, and then be used as a dashboard for the rest of the match, so for 95% of the game its an output onto the screen

That may be enough to power a microcontroller by itself, but the driver for your display alone is going to draw considerably more than that.

could the 5v lines be connected in parallel?
