Summoning @Martin-MT as a reviewer too.

Yeahhh! Thanks for adding this! 🚀

Would it be convenient to add a "how to start" section for using platform io with this project or the links in platform io are pretty well guided? I haven't tried it locally yet.

Good idea! I improved the README file accordingly (PlatformIO docs are pretty good though!).

Great stuff! LGTM!

[Martin-MT]

Other than the uController being the ATmega328p (the one without the p is no longer acquirable), it LGTM.
Older versions of PlatformIO used to add more stuff to the .gitignore, but tried it myself with the newer version, and it generates something just like the one you added.

Great, thanks @Martin-MT and @francocipollone !
