John:
I haven't try it with PIC but this is
what I would do first.
16c71 or any 7X family pic use analog input.
you need at list 1 resistor like 100 k or 1mohm  to ground.


do this

1. make input analog
2. start conversion
3. check for end of conversion
4. load result in w
5. xorlw b'00000001'
6. check z flag
7. if set then party time
