I’d definitively stick to the components used in the book. Otherwise you need some experience with I2C. The project will be hard enough for a beginner.

If you’re taking the web out of the equation, Exercism’s elixir track is a good place to start. They’re not more complete projects in the way I think of those, like the weather station one mentioned earlier but the exercises are a good slow progression beyond the basics.
As a beginner, I found Elixir koans to be another good introduction to the language. The compiler error messages almost give you the answer sometimes but you can run through them very quickly. For me, they helped solidify the topics I covered in the docs.

Yes AoC is not for beginners. But if you like that kind of riddles take a look at Exercism. You can get a mentor there to help you and you can always get help here.
EDIT: two people recommending Exercism at the same time. Must be good.

Ah, maybe you’re right. I felt that for someone not too familiar with nerves but familiar with the pi and/or familiar with embedded in general it would not be that difficult to adapt with similar components, but yeah, depending on one’s background it might not be right.

Yea, I don’t have much basic-friendly projects, made in other langs.
I’m bad at reading other people’s code, sorry.
Nope, too expensive for me. I don’t have the money for those.
I’m already doing it, I just wanted a bigger thing, like a project, because their exercises is just to pass time, it’s not that hard.
What’s that, there is not much info in the site and github is no better.

It is maybe time to learn what a process is, because it makes a difference.
Solving problems with the help of concurrent processes is why it’s worth learning a different paradigm.
OTP is what makes the BEAM a special place

Agree, especially if Exercism is too easy.
Here is a great project: https://www.peterullrich.com/simulating-game-of-life-with-100000-erlang-processes

What are processes and what difference?
What are those? (OTP and BEAM)
Way too hard and it uses HTML and CSS thing, again not a fan.

Processes are simple unit of concurrency, in Elixir/Erlang.
OTP is Open Telecom Platform, although the name does not reflect it’s purpose.
The BEAM is the Erlang VM.

Ah, okay, seems “easy”
I kinda don’t understand docs… And it’s in a language I’ve never touched either.
