I wanted to play microtonal scales with my MIDI keyboards, so I made this arduino based device that reads in MIDI notes and sends out corresponding microtonal pitches using MIDI notes and pitchbend values. I wrote the code for n-TET microntonal scales, i.e., equally spaced whole number of notes per octave, but I think it could be easily adapted using a pair of lookup tables to map to any scale.
I relied heavily on this Send and Receive MIDI with Arduino instructable. I recommend becoming familiar with it.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
