Hey there.
I am working on a project, where I need an Arduino to read the voltage over a speaker in a television.
I have realized that the voltage is both AC and very low (roughly 0.3-1.3V).
In order to get the Arduino to read this voltage, I would like to both multiply it around 3-4 times, and convert it to DC.
What is the best way to approach this?
I have found this circuit, which I think could do the trick:
Would this be the right approach? Which kind of diodes and capacitors would I use?
Thanks already!
