Creating MIDI Controller with mbed
Overview¶
This final project is based on a Musical Instrument Digital Interface (MIDI) controller. The base idea of this is a device that allows a wide variety of electronic musical instruments or sounds to be played at the press of some buttons. This project uses a mbed hooked up to a PC with the standard USB, and utilizes a C# application on Windows to receive serial port messages and plays sound files. Potentiometers are used as volume control.
