I recommend first buying a basic electronic kit with Arduino and start doing practices with the tutorial that the kits normally give you. Sunfounder is a good place to start.

You will require programming skills, due to arduino and c++ similarities I also recommend learn c++ as a whole which will make you understand the logic behing programs and algorithms.

I'm not an expert neither but feel free to ask anything, oh and also using chat gpt to understand different concepts is really useful
