A friend of mine wants to buy a laptop so he can use Arduino and do a little office for school.
What are the requirements?
And could you recommend one?
My old netbook from 10 years ago is still sufficient for the Arduino IDE. Every reasonably up-to-date notebook should be suitable for office and internet. Only when he wants to use larger IDEs (e.g. Android Studio, Visual Studio or Eclipse or something) does he need more power.
You can also use an older or used laptop.
I don't know what "Arduino" is, but there's something for the office.
