I'm interested if you could put it down.  The program would just translate
the time it tookfor the sound to bounce back and map it on the calc.
Depending on the speed and distance before the sound won't return. I'd do
something like 1 pixel = 2 meters or so.
IF you wanted it to scan (Turn) the RPM of the actual motor comes into the
program.

Here's what I think the output might look like.
