Wind Turbine Pitch Controller, help required.

Hi All

I am totally illiterate when it comes to Arduino but

is it possible for an arduino to measure the digital signal from an anemometer to control a stepper motor using an analog output from the arduino for pitch control?

Also converting the anemometer signal to a moving average of specified readings over a specified time.

If there is anyone out there who can write the programme for me full marks!

No, you can't control a stepper with an analog output. That's not how a stepper motor works. You send stepper motors pulses to make them move and the timing of the pulses decide the speed of the motor.

Moving average is trivial. There are libraries to do just that. Google "Arduino Moving Average" and see what you get.

There is a section of the forum called Gigs and Collaborations where you can offer to pay someone to write a program for you. But for that you are in the wrong section. And you haven't said what you are willing to pay. You will also need to give exact details of the requirements.

In this part of the forum it is expected that you write the code and folks here will help when you get stuck.

Thanks

But of course you are correct on how steppers are driven, probably I should have said, to control the stepper forward and reverse according to the anemometer signal.

Yes, arduino can read the anemometer and it can run a stepper. Both of those things are trivial. You just need to write the control logic.

How will the stepper motor control the wind turbine pitch?

The same way propeller pitch is controlled on an aircraft with variable pitch propellers.
