Thank you for replying and sorry if I am unclear. I will try to slow down a bit.

@cfry definitely not necessary to use two Arduinos. I can't really understand where your problem lies.
-The problem is that it does not work when I try to use an arbitrary combination of pins in different modes (Digital in, Digital out, Analog in, Analog out).
Another problem is that I have a hard time reading the code parts that are handling the conversion data in order to do the serial communication, although I understand the principle of it.
You didn't reply to my earlier question about the pinMode calls where you use INPUT_PULLUP on analog inputs. Is this really necessary?
-I assumed that the problem lied in void ()loop as a conflict between the output and input handling sections. And that pinMode calls in void setup() was not relevant in this case. That is why I did not answer that question directly.
Also, why not use the analog pins in an array like with the digital pins? It will save a lot of writing and it's less error prone.
-I was foreseeing that I may want to configure those pins individually, but I can set it up with a loop for now.
One thing you might want to consider is having the Arduino notify Pd when it's done sending all its data and that it's ready to receive. That could be done at the end of the loop() function like this:
Serial.print("done ");
Serial.println("bang");
And in Pd have a [r done] object which will output a bang. Use this bang to send data from Pd to the Arduino by unpacking a list with all the accumulated data, possibly with a [list-abs/list-drip].
I use this notification technique in my 3dPdModular system, but there's a LOT of data there and it was only necessary. Perhaps you could try it out.
-I will try that.
Since I consider this to be basically your code I assumed that you could easily just insert the code for both input and output in void loop() in a way that works and that would show me how to solve it. Then I would be able to do further explorations and it would be end of story.
I will digest this a bit and may start a new thread, since this one has slided from "Having lots of switches into Pd" to "having a working code template for communicating between Arduino and Pd using and an arbitrary mixture of pin modes".
Please let me know if this still does not make sense. Thank you so much!
