Some sort of class helps here a lot - not as much as actual tutoring, but just as motivation and audience that you can show off your projects to.
A tea-making robot you made at your home is boring. A tea-making robot you made during class which participated in end-of-class competition and got 3rd place? Much more interesting.
And if you are in CA, there is Robogames which has (or at least had in the past) categories such as "art bot" (any Arduino project which has a moving part can participate) and even "static bot" (for projects without moving parts). You get to demo your project to few hundred participants, and maybe even get a prize!
