Basically we're building a simple setup with an Arduino board and some motors. The Arduino with motor shield will control several servo motors and DC motors, and possibly talk to a few sensors. This seems to work.
But rather than hook up an XBee, or wifi or something complicated, we'd like to just throw a moto droid into the payload. This would give us A) long range communication through the internet B) a camera we could control via the internet C) realtime video from the droid's camera.
So our question is: the droid has a micro USB port on the side. What's the easiest way to plug that into an arduino (or go-between) and read/write data? I've seen a page where a guy used bluetooth, but I was hoping for a wired connection.
