it's literally the hello world of micros. get an arduino, plug it into the usb, install the ide, new -> example -> 01. Blink. Press Run. Cool you have now blunk a led. Now use AI to draw the rest of the owl.
(Of course, there are those to whom an Arduino is an overpriced piece of junk and they don't understand how I can't solder a three cent chip myself.)
But let's be realistic - all of these things are like my Steam library - purchases made but never used (I have a drawer full of Pis and other SBCs, and Arduino dev kits, etc. Someday I'll have time time time!).
