Is it possible to use a servo with the darlington driver in?
the start here link tells you to take it out, but wouldn't it help keep down the noise that you get, especially with the SRF05?
if the darlington is missing the resistor you place in the holes is gonna connect the output pins to your 28 Pic, else they'll be just disconnected. If you really want to keep your darlington in you could somehow mod it, taking out (or doing something else) two of its pins (one on the left and one on the right) and place a resistor instead.
wait... you could just shift it so you leave 2 pins (left and right) free for the resistor...i think that would work, but i advise you to wait for someone to confirm what i said
the thing i don't understand now is, where does the output connection on the 28 pin project board go if the darlington is missing?
and would it work to keep it in and jump over it with the 330 ohm resistor?
will removing the darlington affect the ability to power other stuff, such as LEDs?
