Hi Nick,

Depending on your load there are a few simple ways. If your load is DC that
is good. If your load uses the same ground as the PIC, that makes it
easier. If you can leave positive connected to the load and switch the
negative, that is even easier. If you answered yes to all three then you
can use an NPN transistor or N-channel MOSFET, and one or two more resistors.

        |           \
--------          GROUND


Cheers,

P.S. You can also use a darlington array if you need several outputs, they
have resistors built in.
