Arduino Mega and DFRobot mini MP3 player
Sarina.Till 2023-07-14 07:01:13 1143 Views4 Replies Hi,
I hope someone can help me, I am trying to work with a mini MP3 player and the Arduino Mega board.
I am using the following sketch:
```#include "DFRobotDFPlayerMini.h"
DFRobotDFPlayerMini myDFPlayer;
void setup()
{
Serial.begin(9600);
Serial1.begin(9600);
delay(2500);
myDFPlayer.begin(Serial1, true);
Serial.println(myDFPlayer.begin(Serial1));
if(!myDFPlayer.begin(Serial1))
{
Serial.println("Problem");
while (true);
}
if(myDFPlayer.begin(Serial1))
{
Serial.println("Good");
}
}
void loop ()
{
myDFPlayer.volume(30);
myDFPlayer.play(1);
delay(5000);
}
```
And I have connected the MP3 player to the Arduino as follows:
Adruino MiniMp3 player
Rx (18)-------------------→ Tx
Tx(19)----------------------- Rx
GND----------------------------GND
5V-------------------------------VCC
Speaker MiniMp3 player
SPK1--------------------SPK1
SPK1----------------------SPK1
I am using the following speaker: https://www.diyelectronics.co.za/store/audio/1502-small-speaker-4-3w-2-inch.html?search_query=speaker+arduino+&results=18
No sound plays through the speaker at all. This is what I see and hear

The SD card has a file named 0001.mp3 on the root of a FAT32 32GB MicroSD card.
I have the 1K resistor set up between the Rx pin and the Arduino.
I have been stuck for days, any help would be greatly appreciated.
Update , it is working !!! I had to replace the SDCard and use the code provided on the wiki .
THANK YOU Jenna !!!!

myDFPlayer.volume(30); //Set volume value. From 0 to 30 myDFPlayer.play(1); //Play the first mp3}

Sarina.Till Hi!
1.Perhaps you can try the example in the wiki. This code is tested on Arduino Uno, Leonardo, Mega boards. It might be worth a shot!
DFPlayer Mini Mp3 Player - DFRobot Wiki
2.pls check the location of the MP3 file.
jenna Hi Again,
Thank you so much for your reply
I have updated the code :
#include "Arduino.h"#include "DFRobotDFPlayerMini.h"
#if (defined(ARDUINO_AVR_UNO) || defined(ESP8266)) // Using a soft serial port#include <SoftwareSerial.h>SoftwareSerial softSerial(/*rx =*/19, /*tx =*/18);#define FPSerial softSerial#else#define FPSerial Serial1#endif
DFRobotDFPlayerMini myDFPlayer;void printDetail(uint8_t type, int value);
void setup(){#if (defined ESP32) FPSerial.begin(9600, SERIAL_8N1, /*rx =*/19, /*tx =*/18);#else FPSerial.begin(9600);#endif
Serial.begin(115200);
Serial.println(); Serial.println(F("DFRobot DFPlayer Mini Demo")); Serial.println(F("Initializing DFPlayer ... (May take 3~5 seconds)"));
if (!myDFPlayer.begin(FPSerial, /*isACK = */true, /*doReset = */true)) { //Use serial to communicate with mp3. 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){ delay(0); // Code to compatible with ESP8266 watch dog. } } Serial.println(F("DFPlayer Mini online."));
myDFPlayer.volume(20); //Set volume value. From 0 to 30 myDFPlayer.play(1); //Play the first mp3}
void loop(){}
I get the the following output:
16:46:32.037 -> 16:46:32.037 -> DFRobot DFPlayer Mini Demo16:46:32.037 -> Initializing DFPlayer ... (May take 3~5 seconds)16:46:33.069 -> DFPlayer Mini online.
But nothing plays through the speaker. I have updated the folder structure on the SD card to match yours. I am using the following speaker - could that be the problem ?
