My "touch circuit" is a piece of grounded wire :)). The pic somehow detects
the touch (I programmed it in PicBasicPro with a simple rctime command that
measures a change) which works fine - except that I cant independently
reproduce it in another PIC at the same time. So I guess my question is -
is there a way to give each pic its own ground? I'm using a standard wall
wart 9 volt adapter with no real earth pin.

Alternatively, if anyone knows how to detect touch on a wire connected to a
specific pin in a more stable way... I'd be pleased to hear about it :))

thanks...
