The DFPlayer Mini MP3 Player For Arduino is a small and low price MP3 module with an simplified output directly to the speaker. The module can be used as a stand alone module with attached battery, speaker and push buttons or used in combination with an Arduino UNO or any other with RX/TX capabilities.
Support for asynchronous serial communication mode via PC serial sending commands
Communication Standard:9600 bps
Data bits :1
Checkout :none
Flow Control :none
We use the AD module keys, instead of the traditional method of matrix keyboard connection, it is to take advantage of increasingly powerful MCU AD functionality, Our module default configuration 2 AD port, 20 key resistance distribution.
Here comes the most simple way to use this module.
note: short time press means pre/next,and long time press means vol- ,vol +
Note: For simple use ,the upper diagram is ready,But if you find the noise is quite loud, then you could attach an 1K resistor to the TX pin.
NOTE: The order you copy the mp3 into micro SD card will affect the order mp3 played , which means play(1) function will play the first mp3 copied into micro SD card. |
NOTE: If you are using Mac OS X to copy the mp3, the file system will automatically add hidden files like: "._0001.mp3" for index, which this module will handle as valid mp3 files. It is really annoying. So you can run following command in terminal to eliminate those files. dot_clean /Volumes/<SDVolumeName>Please replace the <SDVolumeName> to the volume name of your SD card. |
We've created an Arduino library for DFPlayer Mini to simplify the method for you to make it work.
Connect the hardware as the picture above shown and play with the sample code.
