How would I go about making the digital outputs capable of controlling a
higher current than the 5 ma that is standard? Can a switching
transistor be controlled by them? Or do I need some sort of IC to do the
job? Particularly I would like to be able to close a relay when the
digital out is "on". I think the motor control outputs easily have
enough current to close a relay, but I need more than 4.
Thanks,
Todd

| You can use solid state relays with 5 VDC inputs and DC outputs to control large loads. The inputs require very little current. It is less expensive to build transistor switches, which will do the same thing, but obviously much simpler to use (...) (25 years ago, 25-May-00, to lugnet.robotics.handyboard)
