This is a small four button foot pedal for sending MIDI messages via USB.
The case is design to slide together and the ends snap on, so in theory no fasteners or adhesives are necessary. There are three different end cap variations: blank, USB jack, and USB + MIDI jack.
Print two end caps of whichever you prefer, and also print a “top” and a “bot”. Use either momentary guitar pedal footswitches or 12mm buttons (as in the photo).
The controller inside the box reading the buttons is a Trinket M0, but an ItsyBitsy M0 would work better, more code space. The code is written in CircuitPython.
Fusion360 file included in case you want to modify the box easily.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
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.
