I am trying to do a senior design project in which i will remove rectifiers from an alternator to replicate a small scale AC Generation plant. This alternator will be produce an AC voltage to a load. I plan to have a hall effect sensor which reads magnetic field generated the the current passing and send a voltage output proportional to it. I want to be able to send this voltage to an arduino duemaliove board and have it control the current to a certain level. If it is not up to that level. a voltage will be outputted from the arduino to a voltage amplifier (Darlington transistor) and increase the current sent to the feild coils of the alternator thereby increasing the voltage generated. I am curious to of the does this arduino board meet this standard and feasibility?
