The project is an experiment to illustrate that an Arduino can be used to create a real-time audio processing wherein the first set of examples alter an incoming audio signal to an audio output and the second set are outputted computed waveforms.
An LPC2138 microcontroller is used by this project to implement a simple digital audio player where the music files stored on a removable flash memory are played.
The project utilizes an Arduino to produce a drum kit which comes with four piezo sensors, PCB, and other required to make it work with Arduino as a mini shield.
