Arduino USB serial input

Originally I was going to try use JSON coming from a API developer perspective but there doesn’t seem to be much adoption of that for serial comms.

One of the few posts I found discussing JSON at the time (2019 odd as I sat on this post): Sending JSON over serial in Python to Arduino

In the end I decided KISS (Keep It Simple S…) and used comma separated values.

setcustom, 255, 255, 0

Return a ack/OK if all is good.

See the example: open-fusion-led-controller-arduino.ino#lines-214

The other option is new line (\n) only but you are limited to commands with no key value pairs e.g. reboot
