The Intel Edison is one of those DIY electronics boards that we haven't talked a lot about here on Lifehacker, but it's one of the more popular tools for internet of things projects. It's a little confusing how it works at a glance, so Instructables user DangerousTim put together a beginner's guide that covers the basics for setting it up.
DangerousTim's guide walks you through the terminology, setup process, and everything else you need to get started making your own stuff. It doesn't delve further than that, but it's a good starting point if you're just trying to figure out the basics. Once you get through that, you can dig into all the other more advanced projects.
