We created a digital audio effects pedal using a Raspberry Pi; the pedal can accept XLR and 1/4 inch input so it is ideal for horn players and guitarists alike. The effects can be controlled by the knobs and buttons on the pedal as well as by the knobs and buttons on a separate Bluetooth controller, which was coded on an Arduino.
Due to the pandemic, the final deliverable was adjusted; all signal processing and user interface code is complete, but the pedal could not be assembled. Instead, schematics of each device’s PCB and 3D-printed enclosure were designed and priced out for building.
