For a project I need to get nice (as in no spikes or outages) 9V to my Arduino. Unfortunately the supplied voltage can range anywhere from 30 - 60 V (there is no way around this).
From what I know so far, I will need a transformator to bring the voltage down, a voltage regulator to stabilize the power to 9V, and a capacitor (the power may be very briefly disconnected).
That's the theory, now in practice... I have no idea what kind of elements I need to buy to accomplish this.
Can anyone with a little more knowledge of electronics point me in the right direction?
