I did some more testing of my Arduino code today and noticed that I'm getting a fair number of inaccurate speed readings. I found an Arduino library named FreqMeasure that is designed to work with low frequency pulse signals like I've got. Unfortunately, my Arduino Nano Every board has too new of a microcontroller to work with this library. Fortunately, I also have a regular Arduino Nano board, which is supported by the library, so I gave that a try. The FreqMeasure library works much better than the routine I had written. I had to move the speed sensor to digital input 8 to make FreqMeasure work.
