Looking for advice.
I attempted to add some more switches along with 2 Rotary Encoders and a Potentiometer however I could not get anything working. After a few hours I finally got things back (needed a Reset) to where I have 8 buttons again working. I discovered at least 1 problem with Encoders as I had mistakenly created a bridge in soldering.

However, I am still not sure if I have diodes correctly wired. I believe they are wired like in instructions but I have also seen a diagram with them reversed. While I seems to have gotten rid of the bridge it still needs a rewire I think.

I have attached a PDF that shows current setup of 1 column for 3 Encoders (the rows goes directly from switch to Pro Micro rows). The outer pins of Encoder goes to the twin pins - see top picture. The 2 wires in pic go to Pro Micro "D0" and "D4".

Are the diodes correctly wired?
How do I add the Encoder in software?

When I test again I will only try 1 Encoder.

There does not seem a lot in thread about setup of Potentiometers. Is anyone able to give me a pointer?
Cheers
