That's just what I needed. Thank you!

I understand, but what I need to know is how to obtain a variable DC voltage level, which is proportional to the variable AC waveform I'm feeding into my system.

Hi... I have a simple question, yet for some reason I'm blocked and can't figure out how to do this. I have a system which generates a variable AC current . What I need to do is measure this AC current and somehow feed it back to a microcontroller (passing through a ADC first). In order to do this, I guess I need to take the AC current and obtain from it a proportional DC voltage level which I cand send back to the microcontroller. Can anyone help me find the best way to achieve this? Thank you!
