my project includes arduino, push button, dfplayer mini(DFPlayer Mini Mp3 Player - DFRobot Wiki) and a speaker
when button is pressed, the dfplayer mini plays all the song present inside mp3 folder on the SD card.
i am using " myDFPlayer.enableLoopAll() " to play all the songs.
but when there is a switch from one song to another i need a 2sec pause between.
how to add this delay?
