Hello all, this is my first visit here and I haven't even got my Arduino in hand yet (bought but not yet delivered) so please excuse stupid stuff.
First up, I have lots of experience with mains and higher voltage but zero with microcontrollers etc apart from doing a programming course at school on an Apple IIe a year or two back.
I have built a hydroelectric plant on a waterfall on my property, the output is 230v and I use it directly in the house although only on rugged resistance loads until it is better regulated.
When the load (demand from the house) is too high the torque from the generator slows the turbine and the voltage and frequency drop. I am starting to design a system to turn off items in a priority order based on the voltage. By chance, I bought an Arduino starter kit to play with with my daughter and realise it could be a better and cheaper solution than the current/voltage sensing relays I was planning on using.
There are bound to be more questions as I look into this but the first one is. If I buy a wall wart and bypass the capacitor will I have a signal that I can read from an analog input to determine the voltage from my generator? The best way I can see to control the load shedding is by voltage as the output of the generators change with the water level so the max current can change day to day, however, the frequency and voltage seem to be linear so if the voltage is constant the frequency will be as well.
That's a lot of writing for my first post.
Thanks for any help/advice.
