Not sure this is a bug or just an artifact of the hardware I am using

Might be useful to someone else or maybe someone with greater knowledge can fill me in as to the behavior I am seeing.

Until I wrapped the input line with a >0 test the fan would temporarily try to get to the set speed but would then read a 0 and turn it off. Initial speed was 100%.

int input = Serial.parseInt(); if (input>0) { ... } }//End Main Loop

Oh, I suppose you would like details on the hardware.... hah!

Mega 2560 With a fan from Bgears: https://www.amazon.com/gp/product/B07FHM5DJZ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Initial RPMs are correct at around 5300. Once I change the RPMs the reported RPMs jump into 15000 range for a 10% duty cycle. I can drop it as low as 4% duty cycle and the fan can't be spinning more than 300 rpm or so yet the serial monitor reports 15.4k

Love the library so far!

Hi, about the first comment, could you try setting the serial console you're using to "No line ending" or something similar? Regarding the second, does changing SENSOR_THRESHOLD value make any difference? Thanks :)

"No line ending" did the trick for it not resetting the speed to 0.

Sensor threshhold did not seem to make much of a difference.

Thanks! Tim
