Hi all!

I need to do some simple interfacing to 220V powerlines.
A PIC16C84 must monitor eight different lights to determine if they
are switched on or not. All the switches are situated together, so if
I could find a way to "tap" the powerlines, and feed this to the PIC,
I don't hafta lay km's of wire to the lights themselves (this won't
be practical anywaty). I'm a little nervous about connecting mains to
the PIC. Also, I hafta keep the component count really low, mainly
for budget-, and space-related reasons.

Anyone have some simple suggestions that could help me?

Thanx!
Gaffs.
