DF MP3 Miniplayer- Plays Sound Clips

The DF Mini Player IC can be used to play mp3 audio files when triggered by the Microbit.

Using audio editing software such as Audacity, or online alternatives such as Twisted Wave, sound snippets can be stored as mp3 files on a micro SD card, which is then inserted into the DF Mini Player. 

Files should be named 0001.mp3, 0002.mp3, etc.p3, 0003.mp3, et

INTRODUCTION

Sing for the moment! The DFPlayer Mini is a small and low-cost MP3 module player with a simplified output directly to the speaker. 

The DFPlayer mini standalone can be used as a stand-alone module with an attached battery, speaker, and push buttons or used in combination with an Arduino UNO or any other with RX/TX capabilities. 

This dfrobot mp3 player perfectly integrates the hard decoding module, which supports common audio formats such as MP3, WAV, and WMA. Besides, the dfplayer mini mp3 player module also supports TF card with FAT16, FAT32 file system. Through a simple serial port, you can play the designated music without any other tedious underlying operation

Connections:

Vcc----->3.3V

GND------>GND

SPK_1, SPK_2-------> 3 watt mini speaker

TX------>Microbit Pin 0

RX------>Microbit Pin 1

Microbit Extension: DF Mini

   Sample Microbit Code:

NOTE: The folder name needs to be mp3, 

placed under the SD card root directory, and the mp3 file name

needs to be 4 digits,  for example, "0001.mp3", 

placed under the mp3 folder.
