Arduinaught1:
I have the Arduino plugged into USB from my computer and nothing happens.I have a 9V battery I could connect to either the Arduino or Motor Shield, will this help?
Powering arduino with USB is ok.
But, from what I can see at : ....click here...
On pages 39 and 49,
There is a JUMPER. Normally, I would remove the jumper. When the jumper is removed, it would allow me to use the USB or the DC power jack to continue to supply power to the arduino, and (at the same time) allow me to connect a DIFFERENT power supply for powering the motors. Where do we connect that DIFFERENT power supply? - It would be connected across the terminal block that says "+M GND" (lower-left terminal block on page 49, right next to the jumper - but make sure the jumper is removed). I believe that the jumper to be removed is JP1. The diagram also has a label called 'JP2', but that 'JP2' is probably a mistake.
