I'm making a remote control (via nrf24l01) that among other things, uses a Dfplayer mini to play select tracks as a sort of sound board. However I'd also like to have several tracks play at random from separate folders.
One for the "random tracks"
Another for the sounds played from buttons on the remote.
So far I have it working where the following sketch plays track "0001.mp3" from folder "Mp3" via an analog switch on the remote.
I'd like to Play Tracks 1-10 via the remote buttons in from separate folder, While a random track (sound) plays once Every 3 min.
I'm using the Makuna Library. and I've tried placing tracks 1-10 in a folder "02" and changing:
"mp3.playMp3FolderTrack(1); // sd:/mp3/0001.mp3"
"mp3.playFolderTrack(2, 1);"
following This reference
Nothing I have tried has worked, I've tried moving files renaming them and the folder from 2 to 4 digit numbers and placing a random track play in the loop with a delay but it locks the button out during play.
Can anyone help? or offer better suggestions on how to do what I'm looking to do?
Thank you!
