The only constant you will want is the one connected to the left side of the shift register you create on your outermost while loop. The shift register will remember the angle you set the previous time through the loop so you can either use it as is or bump it up or down by one before using it. The input to the shift register sets the initial value it will have the very first time through the loop; you will probably want to choose a value that centers the servo.

I am also confused on what a feedback node is. Is it in the same menu as Not, And, Or functions?

You won't find it in the boolean menu, because it isn't a boolean operator. It works with booleans, but it also works with integers, floating point numbers, strings, enumerated values, bundles, basically whatever kind of data you feed it. I can't remember exactly what the name of the palette is where it resides. Now is as good a time as any to learn how to use the search feature in the palette. Type in "feedback" and see what it finds.
