Sparkfun has a nice collection of Engineering Essentials tutorials: https://www.sparkfun.com/engineering_essentials https://www.sparkfun.com/engineering_essentials They explain the fundamental topics of electrical engineering like electricity, circuits, components, communication protocols, signalling and so on in a fun and engagning way. They also sell all of these components with helpful hookup guides. So think of a system you want to make (e.g. conveyor belt), order the components and start building it :) Once you're comforable these fundamentals you might want to look into the design of control/embedded systems. There are quite a few books on these which you could search online for. Obviously, manufacturing lines today are built with more robust and established components but the above would probably be a good entry point to help you start understanding how these things work.
