I have a quick question concerning stacking arduino shields. Can you stack as many shields as you want as long as none of them use the same pins?
I have Ro-Bot-X's robot builders shield as well as a xbee shield that I would like to stack onto an Uno. From my understanding, the xbee shield just uses pin 0 and 1 for serial and breaks out the rest. And then the robot builders shield doesnt touch pins 0 or 1.
