Arduino is the best place to start imo. Get an LED to blink and youve got your intro to intro to electrical engineering done. Teaches you coding, basics of voltage and wiring, etc. You can scale it up and get pretty advanced and go from there.

As a general word of caution though, as someone who does enjoy hobby electronics, please understand that like 95% of what you can make is going to be something that could these days be bought from Amazon or whatever for $15 or less. It can be a fun hobby, but I think it can sometimes feel like you’re essentially just making Knick knacks and toys and overengineered whoozywhats.

This isn’t a bad thing per se, but something to keep in mind.
