Hi friends,
How to measure isolated mains voltage without using isolated transformer?
can we put an opto isolator on port pin?
you
regard
The big question here: Should someone who don't have the electrical knowledge about different methods to measure mains voltage really measure mains voltages?
ni hao friends.
that why asking for opto isolator. no mains for me ^-^
Quartus method splits problem for easy solution.
Does it?
