The goal of this project is to take a traditional piano accordion and turn it into a MIDI controller capable of playing music through your computer. To do this requires solving a few different problems; the finished MIDI Accordion needs to be able to:
Send a digital signal from the accordion keys and buttons to the computer
Convert that signal to MIDI
Play that signal back with music software
Communicate that signal for each button on the accordion
The above goals are enough to have a functional MIDI instrument, but there are a few additional “nice to have” requirements that can also be implemented, such as the ability to:
Communicate MIDI signals wirelessly (via Bluetooth)
Decouple the accordion’s power supply from the computer/wall
Add dynamic expression using the accordion bellows (via barometric pressure sensor)
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
