I tied the power from the lm317 to vcc instead of raw. I corrected it by clipping the pin off of the header for the arduino and jumping a wire from the vcc hole to the raw pin.

I also corrected the drawing, so there are no versions of the drawing with the mistake.

It may also be advantageous to add a jumper to the board for addressing so that only one program is needed for the arduino's.

It is also good to know that the pins on the stellaris launchpad are tolerant of ~8v.
