Thanks God, finally someone made it! I was starting not to be able of following Arduino’s development, this Cheatsheet from The Mechatronics Guy came to save me.
The beauty of it is that you can get all the knowledge at once, but also that the platform has now reached the highschool-exam level. People need the cheatsheet to make it to the exam. I just love it, I will print it and put it at K3′s lab here in Malmö. I bet you a Swedish Crown a lot of people will do the same.
