Pin Out

5v	3.7 to 5v positive input
GND	Ground
A1 - A9	Trigger pins
A10	Stop play button
CN1	Playback cannot be interpreted
BY	High-level output when playing
T	When short - Play background music in the loop until a trigger pin is activated and will start  playing again after the triggered file is over

Memory Card Preparation 

• Format SD card to Fat 32
• Create a folder with the name "01"
• Rename all your music tracks to be "001"-"009" (these match up with the trigger pins)
• Copy all the files onto the SD card into the folder "01"

Sample Circuit

In this sample circuit for testing, we have connected four momentary push button to a breadboard and connected one of the terminals of all the push button to the ground and connected other terminals of the push button to trigger pins A1 to A4. Now, whenever I press a push button the corresponding trigger pin will get connected to ground and the sound file associated with it will start playing.
Watch the below video to understand it properly.

How To Play Sounds?

There are a total of 9 trigger pins so if you need to play the audio file "001" then the trigger pin "A1" should be connected to "Ground". Like the same way when "A2" is connected to "Ground" then the file "002" will play and so on with all other seven files.
