I have been assigned a project to use an anemometer to measure wind speed obviously, but if the speed exceeds a certain rated speed the circuit should turn on an LED. I have just considered having the the anemometer attached to the shaft of a generator and have an LED just connected in series with generator. Thinking that I would have an LED rated for a certain voltage so it wouldn't turn on until that voltage is induced by the generator, but I feel as though that is too simple or if it would work. I am not looking to cheat I would just like some input and ideas on what you may have in mind. And it is an analog circuit.
