I would like to know how to take the AC voltage supplied from a doorbell (usually 8-24VAC) and turn that into a 5V DC signal I can use as an digital input to an Arduino Uno. Is this something that can be done with an optoisolator or relay? I would like 5V DC supplied every time the doorbell is pressed and it to work regardless of the AC voltage the doorbell supplies, as long as it's in the 8-24V range.
I am making this project as a gift, so I cannot measure the exact AC voltage the doorbell supplies, I just know it will be between 8 and 24V.
