Sorry, found the solution.
Three observations:
In loop():
- you are getting wind speed by directly reading a digital pin state. How can that work?
- you are continually resetting your counter, every time through loop(), so thousands of times a second. How can that work?
Outside loop():
- you are not following all the rules about implementing interrupts. You need to study up on that.
Sorry, problem solved.
