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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
