I am working on a project which uses all of the i/o pins on a 16F84.
But I want to add some user indicators to show when operations are being
carried out.  I chose some momentary switches with internal lamps.  I
have already done the math with these lamps and I think it's safe to use
a standard 2N2222 setup.  My problem lies with available I/O lines.  I
have none.  I want to use the same I/O line that the switch is connected
to, since it will not be needed during this time frame.  But I am not
sure if this will work.  I have an idea of what the schematic *might*
should look like, but I am not sure.  I really don't wish to smoke
anything.  Can anyone lend me a hand with schematic ideas an even some
code examples.

Thanks
