Using EEPROM with a Dfplayer mini MP3

Projects Programming

Hi,
I'm pretty new to Arduino and coding so please bare with me :slight_smile:

For my project, I'm using an Arduino nano (Old Bootloader) and a Dfplayer mini... I want it to remember the last track played, so it can play it again on start up. I'm not sure how to do this....

Any help would be appreciated.

Try to imagine we know nothing about your project.

Now, try again.

Never on a first date.

Here you go: EEPROM

Its a melody box. I want it to play a track on startup. It has two buttons;
Left button (short press - play next track, short press and hold volume up increasing volume until released)
Right button (short press previous track, short press and hold volume down decreasing volume until released)

I wasn't able to code my desired button dual functionality. Currently I'm using 4 buttons for the different controls (volume up, volume down and next track and previous track)

Just confused how to communicate to the Arduino which track to write to EEPROM
