midi-usb's Introduction
MihDi - touchless sound generator
- 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
- 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)
