hey all, I've been playing around with capacitors and have a few questions Is it possible to get 5 volts over a capacitor using a AA batery? Or am I limited to 1.5 volts? If I have more than 5 volts going into an arduino pin, that will cause damage. But I can use a voltage divider to drop that, right? I want to use an arduino to control capacitor charging/discharging, but in order to avoid damaging the arduino, I want to use it only for controlling a relay that acts as a two position switch- one position for charging, another for discharging, and for measuring the current going into the arduino. how can I do that second part? if I put a pin between the battery's positive terminal, and capacitor, can I have that go an analog pin for measuring? thanks!
