I have a pretty amateur question about Digital I/O. If I have a device that contains so many digitial I/O pins, say 32, it is relatively easy to get this device to control simple circuits. For example, how difficult would it be to get this device to control so many LED's using the digital i/o?
EDIT: Side note, the LED's will use an outside power source so I am simply wanting the device to act as the switch through the DIO.
