Using a 2803A Darlington array

Hi,

Can I hook the output pins of a Basic Stamp directly to the inputs of a Darlington array such as the ULN2004A or the 2803A?· Or will I need resistors in between?

Thanks,

Chris

    There is no problem connecting the pins direct;· however, it is ALWAYS a good practice to use at least a 220 ohm resistor in series with the Stamp I/O pins.
