Agree. Transistors really are worth learning about to any level - its certainly possible to get lost in the physics. I’d find some high level tutorials online

Agree. Transistors really are worth learning about to any level - its certainly possible to get lost in the physics. I’d find some high level tutorials online that maybe use one of the free circuit simulator tools. falstad.com/circuit/ Nice animation on this site If you are really curious there are many simple circuits you can build. It’s quite a thrill to get an LED to blink with a self built circuit. I’m also a crusty old sw eng. I did spend sometime being a young electronics engineer. Good luck with the journey.
