Excellent, it also provides a tutorial on the site. The box is complete with many things to engage with, I didn't know anything about programming and I have learned a lot in 2 days. It's worth it a lot.

After reading many texts and tutorials, I started my first contact with Arduino using this set, which is perfect for beginners. It has all the necessary electronic components one would need for a first experience, and the accompanying PDFs are well-written with plenty of schematics, code, and theory before starting any specific project.

+ They haven't skimped on the (plastic) box; all components fit without any getting stuck.
- The DC motor included in the kit had a bit of a poor soldering job; it works, but in the second project I took on, the wire came off the motor. (With soldering, it works perfectly.)

I have had this kit for about 6 months. I used it to make my first contact with Arduino. Quite a good set. It contains the essentials to get started. It also includes various PDFs with explanations for installing the IDE, some standard libraries, and PDFs + code with exercises to create small projects with the components it contains.
The components it has are useful for a first contact; you can't create anything specialized.
Perhaps someone could order the components separately and create a kit that is more useful to them.
