What kind of questions will get a reply?

I generally don't click on the vague messages like "please help me" either.

I try to help people, but if there's not enough detail in the question, it becomes more about trying to figure out what the person is trying to do or what the problem is that trying to solve it.

So even if you ask "How can I interface a relay?", if I'm board, I'll point you to the playground link, otherwise I won't answer. But if you're actually trying to get it to work and have a specific problem and explain how it's wired or post the part of the code that should be driving it, it's a lot easier to give a useful answer.
