Remove dependency on platformio for workshop

[willprice]

Whilst platformio is great for library development, I think it's going to be an additional hurdle and confusion if we were to use it in the workshop.

How easy is it to extra a bunch of libs and the skeleton sketch so that we don't have to depend on platformio?

Should be as easy as copying contents of /lib to %USERPROFILE%/Documents/Arduino/libraries; either copying hh_server.* into a new folder in the same or keeping it where it is; and merging hh_clock.* into a .ino file.

Advantages of PlatformIO:

• Cross-platform (including mac in theory, can test?)
• Default C conventions and sensible project structure, including project-level libs (so, for example, challenge2's drawFace doesn't clash with a dependency in another project).
• Can use familiar IDE if they program or we want to inspire programming - including Atom or VSCode
• Platform setup is automatically managed, which is one of our bigger headaches. Basically, platformio run -t upload is magic.

Disadvantages:

• Requires extra installation (python package/extension) and IDE

I find PlatformIO really really useful (bias: I like IntelliSense and I dislike Arduino IDE and all derivatives) so I'm not going to change the master project. Actually, I would really like VSCode to be part of the core software package we ask IT to install because making kids write Node or Python in notepad is awful. Anyway, feel free to create a new branch.

:v:

I strongly disagree, although I loathe the arduino ide I think works very well in the workshop setting. All your points above apply to a real software project but for an introduction to programming I think they serve as a distraction from the real goal.

I appreciate this is your workshop and you're free to disregard my comments but I really think you should reconsider.

Leaving open until tested further with both PlatformIO and Arduino IDE.
