Step 2: Maker audio 
*We'll need a tool based Sto oX and choose the right conversion program according to the work frequency of your Microduino modules; 

*Unzip the audio file, enter the folder "Microduino with 16 MHz", store the file into the folder and drag it to "FullRate@16MHz_Mono.bat" for batch processing;

|
*The program can be converted after the drag. A dialog box will pop up, showing "Enter Any Key to Continue..."; 

|-
|

|-
|
*After it is finished, you will find a newly-created folder and the converted file is just inside it. If not, you can convert the original audio file to "wav format" and try again.

|
*Cope the converted audio file to the memory card and insert the card into Microduino-SD card slot. 
*Use IED to open the test program offered by Microduino, choose the board "Microduino Core (Atmega328P@16M,5V)" and download the program. Before the download, you should know:
**Since some libraries may have different pin definition, please download the latest libraries to replace the former ones; 
**In the program, you need to change the name of the audio file to that of the generated audio file. 

==Result==
