OK, that is what I was concerned about. That photosensor isn't exactly a speed demon. It needs a wide stripe. The wider the better (up to 180 degrees of arc, no more).

Yes, that's the "period" method (method2) that I was talking about in my previous post.

How exactly do I go about programming that?

If you're using
this, you're already doing it.

The code doesn't look right to me, but I'm not a LabVIEW guru. It looks like you are converting the period to rpm, then subtracting the previous rpm value from it, then comparing it to a period. Bill or Mark, can you please jump in here and help him?
