Hi you all!
I'm Marc, from Spain, winner of the last GSBC - best photo.
I have done some slides for newbies about the use of an Arduino in Near Space projects, you may find the slides interesting!
I attach the slideshare link for the fist lecture -in my profile are the following three. Feel free to download, share and give me feedback!
All the slides (if you don't have a linkedin/slideshare account)
