Dagu Rover 5 chassis robot demo

Yeah, I was just going to use (for now) a 9V smoke alarm battery to power the board and 6 AA batteries for the motor.
So I was thinking to engage the Arduino board to cycle through the program I write I'd just slap a swith between the Arduino power supply and the Arduino board. So I would have a flip switch or something similar. Do you think this would suffice?
