Hello,
I was very interested but…
When I did a cut and past of your code the first thing is the quotes are an issue.
I will have to do a song and dance to convert the formatting and I won’t.
I you post clean formatted code that can be run in Processing or viewed in an editor of my choice I may look at it.
I did some exploration last year with Arduino to server with hardware device:
And also with Processing using the hardware.
Hardware devices:

It would be interesting to do Arduino <> Processing <> Server (> is “to”, < is “from”) some more.
