Application Experiment For Arduino:
1.Hardware preparation:
Hiwonder series MP3 module
TF card reader
Board for Arduino UNO
Expansion board for Arduino
4PIN cable
USB cable

2.Tool software list:
IDE for Arduino

3.Wiring preparation:
Board for Arduino UNO + expansion board for Arduino, use 4PIN line to connect the MP3 module to any C port on expansion board for Arduino.

Note:
- If you do not use the expansion board for Arduino, you need to use a Dupont cable to connect the module to development board for Arduino.
- Other items pictured are not included, for demonstration purposes only.



4. Experimental Process:
1) Insert TF card into the USB port of computer through card reader, and create a new folder named "MP3" in the TF card;
2) Add the required audio file to this folder, the file naming format is four-digit number + audio file name (audio file name can also be optional), such as: "0001 little apple" or: "0001";
3) Insert TF card into the TF card slot of the MP3 module;
4) Connect development board for Arduino UNO with expansion board to the computer through the USB cable.
5) Open the program with IDE for Arduino.
6) Open serial port monitor and set baud rate, upload sample program.
7) The MP3 module will automatically play the audio in the serial number set in the program.
