Hi there,
I wondered if anybody would be able to help resolve an issue with the current code I'm using to run a DFPlayer Mini and 7 segment display (TM1637) from an Uno. The code currently seems to skip through the mp3's really quickly (0.5 - 1 secs of each song).
Video available here:
Also attaching an image of the circuit.
Thanks for taking a look!

/* 04_dfplayer_mp3_test_nextbutton
* This is LCBBs basic mp3 test code (based on DRRobot's DFPlayer code) for sequential
* mp3 playing tests and basic functionality. Other related code including more advnaced
* functioanlity and LED track displays can be found at:
* https://github.com/LetsCodeBlacksburg/arduino-mp3-player
*
* This version cleans up the playback code a bit and adds
* structure for reading buttons and navigating playlists. This
* version is also best suited for tracking the song # for
* displaying on a display device.
