For a practical understanding of electronics, there's no need to go so far deep into the theory that you'd get "lost in all the electrons". I really like HyperPhysics for the basic, basic theory - http://hyperphysics.phy-astr.gsu.edu/hbase/emcon.html#emcon http://hyperphysics.phy-astr.gsu.edu/hbase/emcon.html#emcon I would go through the Circuit Elements tree first, then the Electric Circuits. If you want to go further, there are tons of college courses with lecture notes available online. You're probably looking for something like an EE201/Electronic Circuits. Here's one I found that seemed to have all the important topics: http://tuttle.merc.iastate.edu/ee201/topics.htm http://tuttle.merc.iastate.edu/ee201/topics.htm Unfortunately, sometimes the lecture notes are hard to understand since they're not meant to be a standalone tutorial. You may also check MIT or Stanford for their free course versions, which probably have the entire lecture. From there, to be honest, I'm not sure what to suggest. One thing I usually recommend to people interested in electronics is to pick up a breadboard kit/tutorial like one by Elegoo on Amazon. It's slightly more programming focused, but it covers a lot of other circuit topics and it's a great way to get started with experimentation. I find that being able to actually produce something as you're learning makes it a lot more engaging. Art of Digital design is a 2nd or 3rd year college level textbook so you might be missing some context there. I would say if you want to go further, look into a transistor-level circuit course (which I took after EE201). That covered both analog and digital transistor circuits, which supported the digital design class I was taking at the same time.
