I have been looking around the web for a solution to my problem but I cannot find anything, so please help me out.
I want to simply connect a DFPlayerMIni to an Arduino Nano which I want to trigger an mp3 file when it powers on. That's it.
I have been using the exact schematic and code from DFRobot themselves (only for Nano)
However I am getting this error:
23:46:18.568 -> Initializing DFPlayer ...
23:46:19.545 -> DFPlayer Mini online.
23:46:20.049 -> Time Out!
23:46:20.182 -> DFPlayerError:Get Wrong Stack
23:46:20.553 -> Time Out!
I find the lack of error codes explanation disturbing. I have no clue what "Get Wrong Stack" means and I am unable to find any documentation that discloses that information.
Any help you can offer, I would be grateful
