school project, the prof did not explain this in class

Hello everyone and nice to meet you all, I’m a newbie on this platform and i don’t know how to use Arduino (1).
A couple weeks ago the teacher gave me this project to do, but he did not explain how to use Arduino 1 or how to connect the attachments on the breadboard.
Can you help me solve this problem or teach me how to solve it, please?
Thanks for your attention.

P.S.
I’m not looking for a solution to copy and paste, I really want to learn how to do this.
The file below contains all the information you need to know about the circuit.
!The text is in Italian!

There are lots of Tutorials, videos, ... in English on the internet.
I bet there will be many in Italian. Arduino was invented by God (in Italy).

Look up:

pinMode()
digitalRead()
analogWrite()

I know that there are lots of tutorials (even in italian) but I don't know C code nor how to combine the attachments on the breadboard.
We use TinkerCad due to CoronaVirus quarantine.
Can you please link me the tutorials that I need to watch to solve this "problem"?
Thanks for helping.
