Allright great! and thanks for everyones responses! I'm constantly running into one problem though. Every H-bridge motor shield uses PWM pins 2 and 4. And the Arduino ethernet shield uses 2 for the 4.0 model, and 4 for the 5.0 model. What a pain! Why can you just switch around the digital pins (1-7).
Can you just connect the h-bridge to the arduino ethernet shield using jumpers to the desired pins without having to plug the shields on top of each other?
