Summary of MP3 player using Arduino and DFPlayer mini
Summary (under 100 words): This tutorial demonstrates building an MP3 player using an Arduino and a DFPlayer Mini module. The DFPlayer plays audio from a TF/SD card (FAT16/FAT32), supports many sample rates and formats, has a built-in 3W amplifier, and offers serial control for play, pause, next, previous, volume, EQ, and folder-based playback. The guide uses three pushbuttons connected to the Arduino to send serial commands to the DFPlayer for previous, play/pause, and next song control.
Parts used in the MP3 player using Arduino and DFPlayer mini:
- DFPlayer Mini
- Arduino Uno (cheap Arduino Uno)
- Small breadboard
- Buttons (pushbuttons)
- Speaker
- Resistors
- Wires
- Jumper wires
Hi guys, welcome to this tutorial. Today, we will build an mp3 player using an Arduino and the DFPlayer mini MP3 module.
The DFplayer mini is a compact and affordable mp3 module with a basic audio output that can be easily linked to a speaker or headphones. The module can operate independently with a connected battery, speaker, and buttons or be paired with a microcontroller such as Arduino, supporting RX/TX communication. By sending serial commands, we can play music and control functions like switching songs, shuffling, and pausing. It features an SDcard slot and works with both FAT16 and FAT32 file systems.
Included in the DF player mini are a variety of functions.
- Support of sampling rate of 8KHz, 11.025KHz, 12KHz, 16KHz, 22.05KHz, up to 48KHz
- 24-bit DAC output, dynamic range support 90dB, SNR supports 85dB
- Supports FAT16, FAT32 file system, maximum support 32GB TF card
- A variety of control modes, serial mode, AD key control mode
- The broadcast language spots feature, you can pause the background music being played
- Built-in 3W amplifier
- The audio data is sorted by folder; supports up to 100 folders, each folder can be assigned to close to 1000 songs
- 30 levels of volume adjustable, 10 levels EQ adjustable.
The purpose of this tutorial is to show how to utilize this module with Arduino by using push buttons to direct Arduino in sending serial commands to the module and managing mp3 playback. To accomplish this, we will utilize three buttons. The initial button will act as the “previous” button in order for us to play the previous song. The next button will pause/play the current file and the following button will play the next file in line.
