I guess it's 6 of one half dozen of another. I still need to run that through a voltage regulator and then a transistor switched by the 5V PWM from the Arduino. So whether it originally comes off the 12V out from the Arduino or right off the 12V power supply probably makes little difference functionally. Although I may be able to do something more compact with a proto shield on the Arduino itself using the 12V Vin as you suggest.
