The aim of this project is to build a practical portable music player that is compatible with common hardware and files (standard batteries, microSD cards and .mp3 music files, respectively). The ultimate goal of this would be to have a music player that can be built from scratch by anyone, and which is able to play music files without relying on cloud services.

A DFPlayer Mini module will be used to read the .mp3 files inside the microSD card and will output the decoded audio. The DFPlayer will be used instead of a conventional SD card reader due to the difficulty in decoding mp3 signals on an Arduino.

The Arduino will control the interfacing with the user (control buttons for input, an LCD display for output), as well as the functions of the DFPlayer (play/pause, track selection etc.).

The LCD Display will show information such as the current track. The buttons can be used to play/pause and navigate, as well as increase/decrease the volume. The audio can be outputted to earphones (through a 3.5mm jack) or to two stereo speakers (powered by an amplifier).

O arhivă (sau mai multe dacă este cazul) cu fişierele obţinute în urma realizării proiectului: surse, scheme, etc. Un fişier README, un ChangeLog, un script de compilare şi copiere automată pe uC crează întotdeauna o impresie bună .

Fişierele se încarcă pe wiki folosind facilitatea Add Images or other files. Namespace-ul în care se încarcă fişierele este de tipul :pm:prj20??:c? sau :pm:prj20??:c?:nume_student (dacă este cazul). Exemplu: Dumitru Alin, 331CC → :pm:prj2009:cc:dumitru_alin.
