Other Hardware Displays

Hi,

can you please tell me if it's possible top connect a 3x4 keypad and a e-paper at the same time to an arduino uno?

I have connected an e-paper at pins 7,8,9,10,11,13.

Where can I connect the 7 pins for the keypad?

Thanks and regards!

As @UKHeliBob writes, the analog input pins are digital pins with analog read as a special function so they have all of the attributes of a digital pin.

You are welcome, but @UKHeliBob provided the solution. I just elaborated on his post.
