I'm running a Duemilanove with an XBee shield. I need the Arduino and shield to be far away from my computer, and was expecting to run it on a 9v battery. Unfortunately, the 9v is apparently not enough to power both the shield an the Arduino (I'm guessing it's a current issue...?) Is there a way to power the shield separately or give the board enough juice to power both? Or do I need to find another way to interface the board with my XBee?
