Problem is that, this is my semester project and deadline is in next week. So thats why i want this urgently. Plz sir send me this project

I think you just stepped in it.

We can provide help with homework assignments. We don’t provide homework assignments. Even if we’d do, there’s not enough information to go on to even start thinking of how this could be done.

So it sounds yet another case of “oops, I should have started this when I got the assignment instead of letting it sit for a month or two”.

Anyway, if you’re serious about this project, start here. You were obviously too lazy to even read that part (or didn’t care about following the instructions given in it) - but you can still correct your ways.

I have make already done some work on it. I have made ac voltmeter. Which measures generator output voltage and showed it on arduino serial monitor. I want when pin of arduino works as variable dc supply and it should connected to rotor of generator for feedback when voltage of generator drops. That variable source from arduino pin give suitable voltage to rotor in order to maintain output voltage.

So you did some work! Why didn't you tell so right away? Now you're getting somewhere.

Arduinos (the regular ones - Uno, Micro, Mega, etc) can not produce a variable DC voltage by themselves. You can produce a PWM signal using analogWrite() function. Feed that to a low pass filter and you can produce a variable DC voltage. Depending on your generator's input impedance you may have to buffer this through a unity gain OpAmp circuit.

Finally, the best way of controlling the output based on the input is probably through a PID function, there are PID libraries out there to make this easy for you.

0-5V variable supply i have made but i want 0-30V variable supply.how can i do this?

Interesting fact!

Teachers also come to this forum to see what students are asking for help and what students try to pass other peoples work off as there own.

Google 'using arduino as a variable power supply' and see what you find.

It seems OP is looking for a control signal, not a full fledged power supply. Different thing.

Something like a 6x gain OpAmp circuit comes to mind, but 30V is quite a high voltage for a regular OpAmp.
