Hello I'm using a UNO to measure the period time between two rising edges. I'm using micros() to get a "timestamp" to calculate elapsed time. Then converting it to ms with 3 decimal points But when I'm testing I get some strange results, when the frequency of the input signal gets lower the readin…

Measurements of periodtime more inaccurate when frequency gets lower

Why do you think your precision gets worse?

(5-4.992)/5 == (100-99.86)/100
