In the code, there is obviously a test to see if the MP3 player is properly connected. The problem is that I did some tests (unpluging the MP3 player, removing the SD card) and this test doesn't seem to work, as the monitor keeps telling me "DFPlayer Mini online."
So, I'm not sure my DFPlayer is working correctly.
What could be the source of the problem?
Thank you very much for your help!
Attached my connection and my code
#include <DFPlayerMini_Fast.h> DFPlayerMini_Fast myMP3; void printDetail(uint8_t type, int value); void setup() { //Serial2.begin(9600); Serial.begin(9600); myMP3.begin(Serial2, true); Serial.println(F("Initializing DFPlayer...")); //Use softwareSerial to communicate with MP3 Serial.println(myMP3.begin(Serial2)); if (!myMP3.begin(Serial2)) { Serial.println(F("Unable to begin:")); Serial.println(F("1.Please recheck the connection!")); Serial.println(F("2.Please insert the SD card!")); while(true); } if (myMP3.begin(Serial2)) { Serial.println(F("DFPlayer Mini online.")); } //Set volume value (From 0 to 30) myMP3.volume(30); } void loop() { myMP3.play(1); }
Hello! Sorry for the late reply. I am glad you are inspired by what I did. It's nothing much. I figured out the problem a long time ago. And I will share it with you. There is a multitude of issues that could go on: code, wiring, you name it! I will take a spin at your code (which I am assuming is part of mine (which is probably incorrect)), and will give you what I think is wrong. I will give you some options to try. I will even give you a new schematic/wiring diagram. I am much more skilled at the Arduino thing than I've ever been. Thanks for choosing me! I will, again, look at everything and give you what I found.
And ignorance is not necessarily a bad thing. I was once a beginner at Arduino, too. Now, I am more... intermediate. I use datasheets and stuff, but in no way am I an advance person.
Hello UptownKitten ! Thanks for your reply. Finally, my MP3 player works. I use the DFRobotDFPlayerMini library. I don't know why but it seems that the other library ( DFPlayerMini_Fast) doesn't work with my MP3 player.
