I am using an arduino uno + mp3 mini dfplayer to turn an old radio into a jukebox.
I found most of the stuff i need in the "DFRobotDFPlayerMini.h" library, except for an easy way to change folders. I want to assign a button to "next folder" and one to "previous folder". I only found "void playMp3Folder(int fileNumber);" so i'll have to find a way around it.
I'm thinking of using SwitchCase and make a case to play each folder, or create a function for each folder but i have no idea how to call it.
