Two years ago I created a Daft Punk helmet with animating LEDs for Halloween. That was the first time I’ve ever dabbled in physical computing. Without Arduino, I wouldn’t even know where to begin a project of that magnitude.

If you’re unfamiliar with Arduino or don’t know about open-source hardware in general, then take some time to watch the documentary. Learn why it’s changing our world and helping education.

Now that your mind has expanded, go make something cool.
