Seeed Studio motor shield My goal is to have my Arduino fire two stepper motors.  They need not be simultaneous. I'm using an Arduino Uno with 2 motor shields - specifically, the Seeed Studio Motor Shield v1.0. I know this shield uses D8-13.  

Question is, how can I get the Arduino to use both shields?  Is there a way to make one of the shields take D0-D7?  If I could do that that'd be great. As far as I can tell, there's no way. The motor shields cannot be physically mounted either.
Some shields let you use jumpers or something to change the pin assignments, but I don't believe the Seed motor shield does.  What you can use is a go-between shield between the two shields to remap the pins on the top shield.  Then in your code, you just initialize the second instance using different pins.  You just have to make sure the alternate pins have the features you need, like pwm.
