Raspberry Pi Pico MIDI Gesture Controller: The MagPi Issue 149 @TheMagPi
Extracting an arresting array of sounds from a guitar became a mission for keen coder Gary. In the latest issue of The MagPi, he tells Rosie Hattersley how he built a Raspberry Pi-based expression pedal.
He made use of Adafruit’s MIDI library, and says programming in CircuitPython using Thonny IDE on Raspberry Pi Pico made a lot of sense: “an incredible bit of kit as a low-cost microcontroller, and being in Python-land feels like home.” He also found it to be the best value for money, and the most reliable board for his project. Other components — including the 6DOF AHRS IMU sensor, arcade joystick ball, 3D printer, and neoprene rubber for grip — were bought from The Pi Hut and other stores.
The wiring setup was straightforward enough, with the IMU (inertial measurement unit) and yaw reset button connected to Raspberry Pi Pico.
