Fnm16p mp3 with arduino nano, uno

tcarduino · January 6, 2022, 3:03pm

I am trying to make this project and apply it application for modern project
but currently, I am getting problems and issue
please solve this?
I have currently make proper connections and uploaded my program that was working but getting an error
on serial monitor

DFRobot DFPlayer Mini Demo
Initializing DFPlayer ... (May take 3~5 seconds)
Unable to begin:

Please recheck the connection!
Please insert the SD card!
solve and give me
a solution...
i want to play music after fsr trigger so that why i am using fnm16p mp3 module
but now i am getting error....
while upload program that was successfully uploaded but no one data processed..
and no one music play

code:

So you want help with wiring you have not told us about or code you have not shown, is this correct?

blh64 · January 6, 2022, 3:36pm

You should also request that a moderator move this thread into a more on-topic form, like "Project Guidance".

Installation & Troubleshooting is for getting the IDE installed/setup and working.

@tcarduino, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project See About the Installation & Troubleshooting category.

blh64 · January 7, 2022, 3:19pm

If you look at the link in the code you provided: DFPlayer_Mini_SKU_DFR0299-DFRobot

It would appear you have your RX/TX pins swapped.

Paul_B · January 7, 2022, 9:30pm

So nothing is going to be done about this persistent problem, is it?

sterretje · January 21, 2022, 11:23am

@tcarduino, why did you move it back to Installation and Troubleshooting? Installation and Troubleshooting is NOT for problems with your project; did you read the link that I gave in post #6?

Paul_B · January 22, 2022, 1:07am

Probably related to the reason the OP is having difficulty with the Arduino?

tcarduino · January 22, 2022, 4:00am

I solved my issue which i faced with the pin 10, 11 has been successfully work but now
I want same worked with rx and Tx pin 0 and 1 which is showing same error...
I am getting stuck on my project to complete

What did you do to solve it? If it's code related, post your new sketch; this time, don't attach but post it in a reply using code tags (the </> button).

Please show your sketch that attempts to use RX and TX.

Your original code from reply #5

i have solved previous problem using this
but now i am testing another one to play same using rx and tx 0 and 1 respectively pin in place of 10 , 11.
now want to solved this
soon....

sterretje · January 22, 2022, 10:50am

I don't see your sketch that wants to make use of RX and TX.

Are you trying to use SoftwareSerial mySoftwareSerial (0, 1); ? That will not work.

tcarduino · January 22, 2022, 11:12am

but why?

#include <DFRobotDFPlayerMini.h>

#include <SoftwareSerial.h>

SoftwareSerial mySoftwareSerial( 0 , 1 ); // RX, TX

DFRobotDFPlayerMini myDFPlayer;

void setup() {

  pinMode (8 , OUTPUT);
  //pinMode (3 , OUTPUT);
  digitalWrite(8 , LOW);
  mySoftwareSerial.begin(9600);
  Serial.begin(115200);
  Serial.println();
  Serial.println(F(" introducing force sensor music system "));
 // Serial.println(F("initializing music player"));
  //check SD card connection
  if (!myDFPlayer.begin(mySoftwareSerial))
  {Serial.println("unable begin");
  Serial.println("recheck connecton");
  Serial.println("insert sd card again");
    while(true);
  }
    Serial.println("success to established connection");
    millis();
    //volume control
    myDFPlayer.volume(30);  // volume ranges 10 to 30
    myDFPlayer.volumeUp();
    myDFPlayer.volumeDown();

    myDFPlayer.outputDevice(DFPLAYER_DEVICE_SD);
  // put your setup code here, to run once:
}

void loop() {  // put your main code here, to run repeatedly:

 int fs_reading = 1023 - analogRead(A0);
 Serial.print(" force reading = > ");
 Serial.println(fs_reading); // print the raw analog sensor reading 
 delay(1000);
 
if (fs_reading < 100) //
Serial.println(" - trigger ");
else if (fs_reading < 300)
Serial.println(" - low pressure ");
else if (fs_reading < 500)
Serial.println("- medium squeeze ");
else if (fs_reading < 700)
Serial.println("- medium pressure ");
else if (fs_reading < 900)
Serial.println("- heavy pressure ");
else
Serial.println(" - fool on ");
delay(1000);

if (fs_reading > 600)
{  digitalWrite(8 , HIGH);
   myDFPlayer.play(1);
   Serial.println(" music on ");
   delay (1000);
  }
}

tcarduino · January 22, 2022, 11:13am

but why will it not work?
i have seen a project connection like this so i thought it could be..

sterretje · January 22, 2022, 11:31am

The RX and TX pins on the Uno, Nano and Mega are the HardwareSerial pins that are also used for the communication with the TTL-to-USB converter.

If you want to use them, use Serial for the communication with the player; you will loose the ability to communicate with the PC.

like what i can lose during that
i have tried another one code if anyone got missing and error on the code just let me know first...and help

    while (true);
  }*/
  while(!myDFPlayer.begin(Serial))
  { Serial.print("Unable to begin:");
    while(true);            
    }

result in my serial monitor
it's not working...

blh64 · January 22, 2022, 6:04pm

You can not simultaneously have your serial monitor open AND have your player connected to pins 0/1. You don't get to use a Serial port with 2 things.

If you are using pins 0/1 for the player, you will have to remove all of your Serial.print() calls... and not have Serial Monitor open. And possibly disconnect your player when you want to upload a new sketch...
