Hey so I am working on a project where I need to get the frequency of a wind turbine. So far I have an input to my Ardunio Uno and converted it to voltage, but I am having a tough time with the counters. I am trying to measure the time my voltage is 0 (so I can find the period and then convert that to frequency), but none of the counting functions are working for me. Is there any functions that are recommending for this situation? I have tried the pulse functions but I couldn't figure it out. It would be much appreciated if you could help me out at all! Thanks!
What wind turbine?
What voltage?
How do you measure this frequency?
Frequency of what, exactly?
What code are you currently using?
What does it do, and how does that differ from what you want to do?
Etc.
Long story short, please do read the sticky. The info provided is not useful for offering help.
Measuring low frequencies measuring the time between "pulses" can work well. It depends on how frequently You want to know the result, the resolution of Your Clock measuring the elapsed time between the pulses.
For high pulserates setting up a time window and count pulses can be the best. Just consider the available resources of time resolution.
