Just for kicks, I tried GilShultz recommendation.
For the code in the OP, I edited the Serial.print(',') entries
to Serial.write(',').
There's no 'detectable" change in time with the short amount of code listed. About 5 microseconds to complete the loop() using the UNO.
For those that want to know the difference between 30 "IF" statements vs "IF ELSE", I uploaded some junk code and measured the time. There's a
savings of half a microsecond when the processor checks 30 lines of "IF" vs "ELSE IF".
Now you know. I'll be heading to the car shortly to test the MEGA with
some code and wiring changes. Thanks for making me MORE of a Geek!
