MihDi - touchless sound generator

Dance a Melody

  • MIDI device that outputs notes (relative to distance) over USB to synthesizer or other sound engines.
  • confirmed working on
  • powered over USB
  • enhanced accuracy and frequency in distance measurement utilizing interrupt routines
  • created in summer 2017

Part list:

  • 1 Arduino pro micro (microprocessor board)
  • 1 US-015 (ultra sonic distance sensor)
  • 6 Potentiometer 10kOhm (change settings)
  • 3 2-state-Switches (change settings)
  • 4 LED 5V (show status and frequency)
  • 1 (micro)-USB cable (connect to synthesizer or programmer)

Connections

to arduino board

Pin Device Usage
D2 ECHO US-015 distance sensor receives ultrasonic pulse echo
D3 TRIG US-015 trigger distance sensor to send ultrasonic pulse
D5 Switch1 hold or repeat note on same distance
D9 Switch3 set/unset a minimal distance you need to move to produce a new note
D14 LED1 show frequency of distance measurement
D15 Switch2 change output range between half notes and all notes
D16 LED2 light on sound output
A0 Pot1 volume
A1 Pot2 distance max (1-7 meter)
A2 Pot3 sound duration
A3 Pot4 frequency
A6 Pot5 note height near
A7 Pot6 note height far
5V LED3,4 show power state

Info

  • MIDI output channel is 1, you can change it in code.
  • Coding style is not state of the art, feel free to clean it up.
  • You can ask about the project at MihDi[at]roboschmie.de
