JQ6500 MP3 Player Arduino Library
A simple library to control a JQ6500 MP3 Player Module from an Arduino.
Given

Play a sequence of files, which must all exist in a folder called "ZH" and be named 00.mp3 through 99.mp3 Don't ask me why the folder must be called "ZH", that's what the JQ8400 wants.

that the JQ8400 contains the files...

/ZH/01.mp3 /ZH/02.mp3 /ZH/03.mp3

then the following code will play them in the order 03.mp3, 01.mp3, 02.mp3

uint8_t playList[] = { 3, 1, 2 }; mp3.playSequenceByFileNumber(playList);

pay attention that the file names are 2 digits, "`1.mp3`" is not valid.

Parameters
playListAn array of the numbers of files in the "ZH" folder.
listLengthNumber of filenames in the list.
