Yes, but don't use tis method if you have more than a few inches of wire
total, since the noise pickup is huge.

If you use more resistors, and a cap per section, you can get away with
longer wiring(actually use them as "probes").

You must also change your algorithm, make output low, then input and count
time until pin is high.
