PJRC forum member lokki, who you may recall from their unique MIDI Bass Guitar project, is back with another fun musical creation, this time in the form of an infrared foot controller.

Based on the Teensy 4.0, this project uses USB Host to transmit the X-Y position of an object (such as a foot) inside the frame to a connected computer; sort of like a giant Kaoss Pad for your toes! In addition to the IR frame, WS2812 LEDs along the edges help indicate the detected coordinates, and four big buttons allow the user to switch between modes.

More information and source code can be found on the PJRC forums, and a demonstration can be seen in the video below.
