Hi Travis,
I did do a timing test not long ago for another MWorks user. Please see this discussion.
Also, as I mentioned in that discussion, the Arduino Uno probably isn’t a great choice. I’ve been recommending the Arduino Nano 33 IoT, which uses a much more modern and powerful processor than the Uno. Unfortunately, the Arduino store doesn’t have them in stock at the moment. Although I haven’t tested it personally, the Arduino Zero should also be a good choice, and it is currently in stock.
Cheers,
Chris
