How can I use an Arduino to record the voltage of an RC circuit??
Complete noob here. I would like to lay a simple RC circuit out on a breadboard, and use the Arduino's analog input to look at how the voltage changes across the capacitor as the capacitor charges. I've studied the theory -- I know the graphs and the how to calculate theoretical results, but I want to see real data so I can work with my own numbers. (I have already used the analog input to measure voltage from sensors so I feel as if I have a decent understanding of what is required for that) Of course I could go buy a voltmeter, but where's the fun of that? Thank you in advance for any help.
