    This may seem like a stupid quesition but how do you use the buttons? They are wired to connect the arduino pins to ground when pressed. The standard way to use a button is to wire the pin to ground via a resistor and run +5V to the pin from the button, pulling the pin to HIGH when the button is pressed. For this board do I need to run +5V to the each pin to pull them HIGH by default and let the button pull them to LOW? Am I missing something?

No public wish lists :(
