How would I write code to receive data from MAX Msp?

@woozel

if x integer is sent, servo in x pin opens?

You are combining a few steps and taking a high level view.

The code will take smaller steps.

  if a number is received
     if it is less than x
         move servo 1

     if it is between y and z
         move servo 2

and so forth. Little steps, none of which have the least idea of a concept of to what it is they contribute.

You might start with the reception:

As far as possible I have kept the code examples identical or simplifed them slightly. It should not be necessary to refer to the older Thread, but feel free to do so.
