Once you’ve conquered your fear of static electricity and successfully built a kick ass custom PC from the ground up, making the jump to custom electronics isn’t all that intimidating. The open-source Arduino microcontroller breaks down the entry barrier even further. Flexible, powerful, easy-to-use and licensed-to-alter (under Creative Commons Share-Alike), the Arduino is the linchpin behind scads and scads of nifty DIY electronics projects. And hey! It just so happens that we’ve gathered 25 of the coolest, craziest, and most useful Arduino-powered projects in this gallery for your viewing – and building – pleasure. Mind-controlled Nerf guns, anybody? No, it’s not black magic. It’s the magic of Arduino!
Most of the projects listed include detailed hardware shopping lists, custom software and handy step-by-step instructions so that you can recreate them in your very own Fortress of Geeky Solitude. Unfortunately, that info is too long to recreate here, so be sure to hit the links provided with the pictures to visit the project pages and learn all the nitty gritty details for each project. And if all this microcontroller goodness piques your interest, Make Magazine’s blog and the Arduino section of the Instructables website are great resources for staying up to date with the latest and greatest Arduino news and projects. Now let’s get crackin’!
