So before I go out and buy this motor shield, I was wondering how I could access the digital/analog pins after the motor driver is attached since the motor driver covers up the origional pins. Would it be the same if I use the corresponding pin attached to the motor shield or would the motor shield have altered it somehow? For example, I have a motor shield to power 1 motor. But 1 motor only takes up 2 pins. There are many more unused pins now covered up by the shield. If I also want an LED, well now all the pins are blocked.
