The MIDI Biodata sonification device (also known as MIDI Sprout, by DataGarden) is a great device to make music using plants.
Here I describe how to apply the firmware of the very similar Biodata Sonification Arduino shield to a “classic” MIDI Sprout. This includes adding a button to gain access to a settings menu which allows to adjust MIDI-Channel, LED brightness, note scale and finally the good old threshold.
Sam Cusumano, creator of the MIDI Sprout gave me the idea (or challenge?) to do this:
“And if you REALLY wanna get funky, you can add a button to A1/gnd and use my new codebase which allows users to edit MIDI channel, scale, led brightness, threshold through a ‘menu system’ using the leds and the knob. check it out on my github https://github.com/electricityforprogress/BiodataSonificationBreadboardKit which is an ‘arduino shield’ but should work with the main biodata board with perhaps a few code tweaks.”
