A collection of programs (written in Arduino Wiring and Processing) used to interface with the Olimex EMG/EKG shield.
The actual data writer (WriteSensorData.ino) is based upon the example code provided by Olimex.
The three Processing programs (GraphSensorData.pde, PlaySensorData.pde, and MuscleGame.pde) take that data (obtained from a serial terminal) and output it to the user in various ways.
PlaySensorData.pde depends upon Processing's Minim library for audio output.
