Having just posted Proposal for new close reason -- "Low expertise", "Too Basic", another approach springs to mind.
Instead of answering such questions, we would answer them in a Basic Electronics Community Wiki -- or a set of such questions -- and then close the original as a duplicate. Perhaps a "Basic Electronics -- how to drive high current devices with a microcontroller or Arduino" would be a good wiki question.
If we tag this "Basic Electronics Wiki", we'd always be able to find it easily if we police the tag.
