Hello,

I do not know how to raise the volume of the device once it is plugged in to the computer. I do not know how to write code and would like to have it set at loudest volume possible (31 setting). Is there a way I can do this? Thank you for the help

You have to set it either via programming, or AT commands - check out example 5 here https://learn.sparkfun.com/tutorials/qw … er-library or the pics just below it that show how to change volume :smiley:

Thank you for the response. I am having trouble sending over the serial information through arduino into the board. when I plug the usb out (which powers the device) into my computer it only opens as a drive. Do I need to purchase & attach a FTDI 3.3v breakout in order to raise the volume to max level? Thank you.

You need to connect the mp3 trigger to an arduino board and program the arduino board to change the volume. Directions can be found in the guide TS-Russell linked above.

Thank you YD,

So I will need to buy a Sparkfun redboard qwiic, and use that as the interface between the arduino library on my computer and the mp3 player?

I appreciate the help

Yes, you need a redboard qwiic, the library and code run on that and then send commanfs on to the mp3 trigger.
