Arduino standalone MP3 player
This Arduino-based standalone MP3 player was designed by Jose Daniel Herrera using the VS1002d single-chip MP3 audio decoder, which is a complete audio solution with a high-performance, low-power DSP processor along with working data memory, instruction and data RAM for user applications, serial control and input data interfaces, 4 general purpose I/O pins, an UART, as well as a high-quality variable-sample-rate mono ADC and stereo DAC, followed by an earphone amplifier and a ground buffer. His project uses a SD card module for storing MP3 files and a 4×20 character LCD for providing an user interface for displaying song menu and other information.
