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.
The project is based on the ATtiny12 microcontroller designed for one to three players wherein a random sequence of notes is played and the player(s) listens while singing/humming to mimic the sequence.
