noob Q: Arduino Port C analog v digital

Started by Randy Day February 9, 2016
I can't find any clear info on this, hence 
the question: PortC on the Pro Mini is 
described as the 'Analog inputs' A0-A5.

Do they operate as digital inputs if I
use digitalRead() or read PINC? Or are
they pre-configured as analog, and only 
respond to analogRead()?

I could use a couple more digital inputs, 
and I'm wondering about any conflicts to 
watch out for.

You can use the analog inputs as digital I/O. Just do a pinMode() as you would for any other digital I/O, then use it as a digital pin. You can use A0-A5 or 14-19 as the pin name. See https://www.arduino.cc/en/Tutorial/AnalogInputPins
