I have a motor shield connected to an Arduino Uno, and it's working nicely. I would like to also have a data logger connected at the same time. I see from the data logger which pins it uses, but one of those (pin 12) is currently needed by the motor shield (the 595 chip). I read in the details for the data logger that it is possible, through modifying library code, to repurpose (re-point) some pins, but not all of them.
Here is my question - does anyone know if it is possible to use an Arduino Uno, AND a motor shield, AND a data logger, all at the same time? I'm not afraid of special soldering or programming needed to do this. I'd just like to know if anyone has done this, or maybe recommends against it.
Uno + Data Logger + Motor Shield... possible?

Pin 12 is required by the SD card interface. It would not be easy to change it.
For the motor shield, you would need to do a little library hacking to re-map pin 12 functions to another pin, cut the trace for pin 12 and solder in a wire from the other pin.
