This project converts a xylophone into a MIDI instrument, but not just any MIDI instrument: a Bluetooth Low Energy (BLE) MIDI instrument. This means that it can be setup within range of a Bluetooth connection and receive MIDI data without being tied down with a bunch of cables (besides power of course).
30 solenoids sit comfortably over the xylophone keys, waiting to strike up melodies and chords either live with a MIDI keyboard or playing along with MIDI data from a digital audio workstation (DAW). It has a lot of potential as either a live instrument or for some extra fun in the studio.
Everything you need to build your own is in the guide, including the code, circuit diagram, assembly instructions and some BLE MIDI tips and tricks.
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.
