I had the same problem. All of the open source code is for little toys and the code that is offered with the motor driver is just for demonstration and isn't much help. I came up with some code that worked for me. I'm pretty much a nube too so it's probably not the best but it worked. Ultimately, I gave up on it because I couldn't get the xbees to work and I opted to use a R C transmitter and receiver. Way simpler if you're looking to cop out like me, look into it. Let me know if you want that code. I'll forward it to you.
I'd also like to know if you got your camera to work because I had the same experience with that too.</p>

I've looked all over the internet for sample code to use with a motor driver shield and come up with zip. Can anyone help?</p>

This could cause problems over time if the shield is being pushed to its limits. It seems highly advisable to power this shield directly which in turn will supply power to the Arduino board through the VIN pin, since the Arduino board will draw less current.</p>

I had to modify the board so that the LEDs were disabled and the Vin trace from the terminal blocks didn't go to the Vin pin of the Arduino. The chip on this board is identical to the one on the official Arduino R3 shield, but this one doesn't have braking control. I don't miss the current sense, but having braking control would be very nice. I know why it isn't on the board -- it saves two digital pins. Maybe a solder jumper to enable/disable the feature, like on the R3 board?<p>Nice board, some very minor feature additions would be nice.</p></p>

Regardless, the bigger problem is that only one of the two pairs of output pins (to the motor) appears to be working. This is the case with both of the shields that I purchased. Any advice, anyone?</p>

I have a question, maybe some none could help me iv bought this Ardumoto and an other shield, the Joystick Shield<br>
http://www.sparkfun.com/products/9895 , this one but not the retail version.<br>
My question is:<br>
Can use them both at once on my Duemilanove??<br>

i have the ardumoto bord sitting on top of my Arduino uno and to 12v motors on the 1, 2 and the 3 ,4 pin. The hole thing get its power from a 12v 2amp supply that is conectet to the Arduino<br>
i can massure 11.94v on the + and - pin on the ardumoto bord but i can only massure 8.67v on the motor out pin (1, 2 and 3, 4 pin) when the pwm pins gets the full 255 anlog out from the Arduino. Isent it supposed to supply the motors the full 12v ( or my 11.94V) when its is going at full speed?<br>
thanks in advance.<br>

I want to eventully be able to pop an Xbee shield on and run without the USB cable.<br>
