@ShapeShifter, thanks again.
My idea is to have both Python and Arduino code that is easy to use, and easy to be understood, by someone without much programming experience.
I'm struggling to decide whether what you have in mind fits within that category or whether (even if it may be technically superior) it would introduce too much complexity for an inexperienced programmer.
I will sleep on it.

PS I think I understand why you were looking for a 6-pack of time - you give yours away too generously. Thank you.
