As output, I have always 1 without a dependency from collision or a vibration. rarely I have 0 also.
I don’t undestand where is the error.
With grove ear clip heart rate sensor when I use the clip on the ear I have 1 and when i disconnect from ear i have 0. How can I use to calculate the heart rate?
With GPS I don’t find any example. I don’t know how can I use.
