I'm not sure about what parts he has, but I think he does have some stuff. The gift should be a board that doesn't need too many extra stuff bought. Sadly I can't find any starter kits in Romania.. But I am taking an Uno into consideration.
Also please note: we are a bunch of students (only two of us have jobs, not very well paid..) so the board/kit should come packed with some stuff to get him busy for a bit
or it should be easily ... playable with stuff an enthusiast already has at home. Sorry for not using a tech language but I'm rubbish at hardware. Also thank you for the answers
