I know this is probably long forgotten about, but its worth a shot. Could you give me an idea of what kind of voltage regulator I would need to use to implement something like the second circuit?
Also, would you mind explaining a bit more about how I could connect the motor supply? I recently picked up this hobby, I love it, and I quickly realized the tutorials here (not at instructables, but in general) were similar to most programming walkthru's, full of bad practices and noobie mistakes!
Both circuits are basically wrong. You don't use a regulated supply that feeds the micro and the sensors as well as a nasty horrible noisy motor ;-)
The micro and the sensors can use something like a LM7805 regulator.
