Very cool, Jason. I didn't know you had an online course!
There are also plenty of resources available right inside the latest version of Raspberry Pi OS, if you don't mind reading/following along a PDF. Unless Build-a-Pi changes something.
Click on the Raspberry Pi icon at the top left to drop down the menu items. Go down to Help, and the first item should be the Bookshelf. You have free access to all issues of The MagPi magazine and all the books the Raspberry Pi Press has published (as well as HackSpace magazine and Wireframe magazine). Lots of resources for beginners.
Alternatively, these free PDFs can be found at??Go poke around there, tons of really cool stuff!?
