Part 1: DF Player Mini - a mini cheap mp3 player

Introduction

I am fascinated how easy it is to build an mp3 player using a DF Player Mini. DF Player mini is a cheap mp3 player.

Bill Of Materials

1. DF Player mini
2. Breadboard
3. Battery / power supply
4. Speaker
5. A couple of jumper wires
6. A micro SD card with some mp3 files loaded.

Hardware Instruction

1. Insert the micro SD card to the DF player mini.
2. Place the DF player mini to the breadboard.
3. Connect power supply +5V to VCC pin (pin 1, please refer to below picture)
4. Connect power supply ground to GND pin (pin 7).
5. Connect the speaker – pin to SPK_1 (pin 6) and speaker + pin to SPK_2 pins (pin 8).
6. Connect a jumper wire to GND pin (pin 10)

Basic Operation

So basically, IO_1 and IO_2 is used as follows:

1. short press IO_1: play previous
2. long press IO_1: volume down
3. short press IO_2: play next
4. long press IO_2: volume up
