Hey
I want to make AC voltmeter using microcontroller. To feed this voltage to microcontroller first I need to scale this AC voltage to controller's input voltage range. For that what should be methods to do this. Or what are the options ?
voltage range: 0-500Vpp.
Method in consideration: Simple voltage divider.
what else ?
