I've been browsing the Arduino forums for years. I have no idea why I find it so fun, but after all this time, I see the same frikin problem over and over with posts!
People never include schematics/drawings! 90% of the questions the OP asks why his code isn't working, and the first 4 comments are "Please post schematics". Most new people don't understand how it's usually quite helpful to have the entire scope of the project laid out for those trying to help.
Wouldn't it be nice to have a pinned post at the top of the forum that outlines how to ask a question? It might save these new users as well as the helpers a little frustration. Or, when creating your first post as so many folks are, there's a template that you are presented with to overview before creating your first post.
Just my thoughts.
