pin A6, A7 pushbutton

Hello,

I want to input signal from multiple pushbuttons into a single pin. I plan on doing so with different value resistors and using analog pins. My question is, what is the difference between A6, A7 and the other analog pins? From what I've read they cannot digital write but I don't think this would affect my application. Can I use these pins for my pushbuttons?

Thanks!

Yes, you can use them. They are analog input only. The A0...A5 are also digital pins.
You have a Pro Mini, a Nano or a board like that ?

Yeah a mini pro 3.3V. I just wanted to know if it would work. Thanks!
