The Arduino is a cheap electronics board that allows you to make your own electronics without a ton of coding experience. We love the Arduino, but like any electronics project, coming up with ideas for what to build is tough. Whether you’re just looking for inspiration or just need a place to start, let’s take a look at ten of the coolest Arduino projects.

Note: even some of the ones marked Easy may not be so easy – also some require expensive extras.
