Hum. Or maybe a walkthrough.
This is a very cute and easy top understand video on what an Arduino is, and what it contains (here). It is produced by the YouTube engineerzerochannel. They have several other videos, most of which are run-throughs of small, easy to program Arduino functions and projects (autofade lamp… tea dunking machine..?)
“Remember – no matter how big or small, Arduinos are FUN!”
