Grove Hall sensor

Hi Everybody,

I’m using the Grove hall sensor with the code MeasureRPM from FrankieChu. I have a small motor working with wheel and magnet - south face. The magnet turn until 3500tr/min in front of the sensor. I’ve got Arduino IDE 1.6.7.
I didn’t change anything in the code but it doesn’ work.

Could you help me please?


This Demo code works in Arduino IDE 1.6.4 perfectly.Can you please try and let us know if you have the same issue.

Thanks and Regards
