arduino-mp3-player

A home made mp3/ogg/flac player based on an Ardnuino Micro, a VS1053 DSP and a 128x32 SPI OLED graphic display. Watch a demo on youtube.

Arduino micro connected to DSP with an OLED display

Parts

Pin setup

To connect the DSP, use the Frank Cohen’s wiring diagram. Beware, there’s a mistake on the DREQ connection from the DSP that should be connected to the pin 3 of the Arduino (and not the RESET).

OLED display is connected as described from tutorial, using Arduino PIN 9 to 12, using "software SPI" (distinct from VS1053 "hardware" one - using same "hardware" SPI causes artefacts on display).

5 way button is connected to Arduino PIN A0 using multiple resistors like described here.
