If you’ve ever experimented with MIDI, you’ll either adore or be infuriated by the way that you can tinker with everything. Sound-waves are really just applied mathematics, so
generations of geeks have poured their hearts and souls into the pursuit of the perfect wobbly tone.
This 3D-printed foot pedal for MIDI is relatively simple by comparison with a lot of MIDI projects. It entails just one 100K linear potentiometer, an Adafruit QT Py RP2040, some M3 fixings, and a USB-A to USB-C cable. That, and a beautifully designed and executed foot pedal chassis, designed by Adafruit’s Ruiz brothers. As always, the source files are available for anyone with space on their printer bed – in this case you’ll need at least 210 × 210 × 100 mm.
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.
