Best Arduino lessons for different age groups? Answered
I'm always looking to freshen up my curriculum when it comes to introductory Arduino lessons. Some older guides have mistakes that aren't ever corrected, and new features come out that I just don't notice (my students tease me for forgetting about the bulk comment/uncomment menu item, for example). Besides the Instructables Arduino Class and Tinkercad Circuits lessons, what are your best suggestions for introductory Arduino lessons at the grade level you teach?
