Your sketch failed here too. How exactly did you include the DFR library? When I replaced your
#include "DFRobotDFPlayerMini.h"
using Sketch > Include library > DFRobotDFPlayerMini
it worked OK.
I prefer angle brackets, not quotes, like this,
#include <DFRobotDFPlayerMini.h>
because it confines the compilation search to my \libraries folder.
If that doesn't fix it, check your wiring again and connect a jumper wire to the IO2 pin of the module (pin 11) and briefly touch it to ground. Assuming you do have more than one file on your mSD, that should play the next one with each touch, proving your module is working.
i have a file named 0001.wav in root of sd card and sd card capacity is 8 giga byte
on my dfplayer printed dfplayer mini - hw-267A and v0.5.1
i have changed
"DFRobotDFPlayerMini.h"
with
<DFRobotDFPlayerMini.h>
it dosnt work
also any leds in dfplayer mini is not on
could problem from dfplayer or power ?

there is only one file named 0001.wav in root of sdcard and its playing normally without problem in windows player , yes this is my first time with this dfplayer module
Hello. Did you ever figure out what was happening with your DF Player
Minis? I ask because I’ve been using them for years, probably used 20 of them without a hitch, however I just recently bought a new bunch, and these ones do not work for me.
