Thanks. No, I don't really want something close to programming, I just mentioned it to say thats the closest thing I know.
I want to learn electronics to be able to upgrade or replace parts in devices which allow that (like disco light equipment), as well as add custom things to them like internal battery. And not damage/break anything in the process. But I don't care how the laser/light modules and their drivers work internally, just how to connect them together properly.
