Start with SNAP CIRCUITS toys. Even if your an adult, these are a start.
Then upgrade to a ELEGOO UNO Electronics kit off Amazon.
It’ll give you the basics of powering stuff, and then basics of signals.
Some kind of RC Car, Multicopter, Self built 3D Printer hobby will also help get you started.
Interesting idea,
But search sites currently can’t find anything in lemmy.
So how will they link to this?
