Can Analog pins be used as digital pins?

The Analog pins can be used as digital out, can they also be used as digital in?  and does the reference voltage need to be connected for them to be used as digital pins?


Thanks again!

You can use all pins as digital IOs (in and out) regardless of your analog set up. In fact the analog portion doesn’t technically even have to be powered for those pins to work as digitals.
