The designs for all those wonderful Arduino and electronics projects don't create themselves, sadly. No, a person needs to put in time and effort laying out the circuits and carefully arranging the components, often by hand, but sometimes with aid of a software tool. A new player in that field is CircuitLab, a surprisingly full featured app for sketching out schematics and simulating them that lives entirely in the browser. It's also amazingly user friendly and simple for even the novice hobbyist to dive into. Finally, once you've finished with your project you can make the design public and share it with others.
