Hello everybody. My question is about how to measure AC voltage with Arduino? I have 3 AC 230v outputs and I want a standalone arduino to measure those 3 voltages and I don't want to use transfomer for this. I was thinking of voltage dividers but probably I am gonna burn the Microcontroller this w…
