PT785-S Pan and Tilt System + Arduino

I bought one of these a little while ago and finally got around to testing it with an arduino. This system isn't accurate enough for real-time repeatable motion control photography IMO. I'm planning on using it for capuring sphereical longitude/latitude HDRI's.
