Programming language to interact with electronics?

I'm very new to this but I have a question.
I want to learn a programming language which can be used efficiently to interact with electronics. I'm not sure how or what yet but I'm going to make it a hobby and learn it over several years.

I already know C++ but I thought that something like Assembly language might be my best bet. Is that the case?

I also know that there's micro-controllers out there such as Arduino to do all this but I want to learn how to get my programs to turn things...
