2) AD KEY Mode

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.

3) I/O Mode

Here comes the most simple way to use this module.

note: short time press means pre/next,and long time press means vol- ,vol + 


 

Connection Diagram

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. 
 

Copy your mp3 into you micro SD card

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.

For Mac User

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.

Sample Code

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.
You can download the latest library here: DFRobotDFPlayerMini.
