This is a quick and easy project that will be speed your work on future projects. By combining an Adafruit BlueFruit EZ-Key with a foot switch, we end up with a wireless, hands-free scroll button. No need to put down that hot iron to see the next step in the tutorial. Just give the pedal a tap with your foot to scroll down the page.

Works with any operating system (Mac, Windows, Linux), tablet or phone (including iOS & Android)!

Would you rather have it jump to the next page instead of scroll? No problem. The BlueFoot can be configured to send any keycode you want. Program as many as 12 keycodes into the EZ-Key and use a jumper to quickly switch between them.
