Many thanks, had/have a couple of dfplayer boards and assumed both had blown because I couldn't get anything out of them, not even the LED. Video was extremely useful, now to integrate to Alexa!

[@FadsToObsessions]

Great to hear - if you have time, would be very interested in your results with Alexa

[@jezwalter2440]

The basics are, to get around the DFPlayer file naming restrictions, I will use a PHP routine to read all track and artist names from current local files and load this text into a database table. A column within the same table have consecutive numbers for each file. The file will then be copied to an SD card using the new index as the new filename with leading zeros where needed. New tracks can then be added to the end of the table quite easily. You can ask Alexa for any words within the track title or any words within the artist name and Alexa would use the correct index through a simple query carried out by Alexa. This would then be sent to a tiny D1 mini which sends the commands to the DFPlayer. Stay in touch for more info.

You are a Genius! This is just what i need. One noob question, ¿Is there a volume limitation?

[@FadsToObsessions]

Thanks for the kind words (but unfortunately, far from a genius 🤓). The component has a built in 3W amplifier that can direct drive 8/16ohm speakers, with 30 levels of adjustable volume within that range. The speakers I used in the video, salvaged from an old analog TV, were "plenty loud" with the module, and I generally only used it about mid volume (otherwise too loud in a normal office/bedroom sized space). Take the normal care with earphones, it can be very loud with them.

[@m3lateef]

Very clear explanation, thanks. May i ask what is the best battery and speaker to use if i want to create a tiny mp3 for kids?

[@FadsToObsessions]

The MP3 module requires DC 3.3 to 5V, so just 3 or 4 series AA or AAA batteries probably suffice (likely least expensive option), but perhaps a 3.7V LiPo pack would give you smaller size (and be rechargeable), something from RC drone/car maybe suitable. In terms of speaker, any 4 or 8 ohm speaker (perhaps salvaged from discarded item, or search ebay using "4 ohm 3W mini speaker") - best if you can use a salvaged speaker/items, otherwise, overall cost starts to increase quickly (and likely just easier to purchase ready to go commercial MP3 player - unless to want to customize in a particular way).

[@m3lateef]

@@FadsToObsessions Clear. Thanks a lot

[@aussieweaboo1054]

Great video you are to be commended, just a quick question. Without using the arduino setup What would happen when the song ends? Will it play the next song on the sd card? Is it possible to have the song play Once? at a push of a button and when the song ends it simply stops until you press it again? If you had just the single file on the sd card?

[@FadsToObsessions]

Using the "ADkey control" (i.e., without Arduino and using the resistor ladder setup, section 4 page 15 of the datasheet) if use 33K resistor, the function is just play (or pause if playing) the "current track" (which if only one file on the card, will be that file) and then when the track is finished, the player stops (and if press 'play' again will play the same song). To get the previous or next track, would need to use additional buttons with 24K and 15K resistors respectively.

[@FadsToObsessions]

Figure 5-5 in the datasheet gives the resistor values for each "key" and the function each "key" provides is listed in the table at the start of section 4 of the datasheet (or there is a diagram at the start of section 4 also) - so for example, K7 (key 7 is "playback track 4) which would be a resistor 9K1 ohms.

[@MrDonrecardo]

Great video , but can you answer me a question. I am making a sound generator for a model steam train. I only need to play one sound file that goes " Chuffff" and that only lasts about 1 second . I need to trigger it relative to the trains speed so when its running slow it may get triggered every 2 seconds ," Chuff silence Chuff " etc. when it speeds up a little perhaps 1 trigger a second I would get " ChuffChuffChuff" . All good so far but now we get quite fast and the triggers come faster than it takes to play the full sound sample , What I need is for the trigger to cut off the current playback and restart it from the beginning so I get " ChuChuChu or even ChChChCh. Is this possible and if so how ? I dont want it to have to wait untill each chuff has played out its full length . I had planned to use an optical interupt on the trains axle but I worried that if the train stopped with the optical trigger closed it would keep repeating but I suppose using an MCU I could get it to trigger an interrupt on a rising edge so if it stopped when interupting it couldnt play again until the trigger from the optical sensor dropped low and then high again. Sorry for the long post but if you could let me know if and how the sound can be stopped and restarted back at the beginning I would be grateful ..... Don

[@FadsToObsessions]

Don, the DFPlayerMini will restart playing a track/sound file as soon as it receives the command from the MCU, and the existing track (if any) will immediately cease playing "automatically". I have a couple of examples showing how to repeat playing tracks (both looping through files and replaying at set intervals) kzbin.info/www/bejne/f4LVZ4SKrtShqZY and kzbin.info/www/bejne/q5XKl5JjrZV9p6s The only "limitation" is that there is a "seek time" involved with the electronics within the DFPlayer Mini getting the info/data from the SD card etc. This means there would be a brief pause between "repeats" (in the order of 10's of milliseconds, but enough to be noticeable when listening) - annoying if trying to get a "continuous" sound from a "sound clip" for example, but in your application, perhaps fine.

[@MrDonrecardo]

[@spaceadventurer100b8]

[@kevinmithnick9993]

or you can build a decoder

[@microduty6190]

I'm using the DFPlayer Mini in the standalone mode. I've set it to "loop all" by connecting a 51 ohm resistor from pin 12 to ground. It works fine but in that configuration, the volume adjustment function (via the I/O pins) stopped working. Is that by design? If yes, is there a workaround? Also, there is a time gap between songs in the loop mode. I know the gaps are not from the songs as these sound files were edited without any gaps to be played seamlessly. Is there a way to remove the gap between songs?

[@FadsToObsessions]

If I understand your setup, you have a 51Kohm resistor directly between pin12 to ground, and then other resistors (of appropriate value) connected from pin12 to ground via momentary push buttons, for the other functions (e.g., ~25Kohm for volume down). This means the DFmini is "seeing" a resistor value of 51Kohm all all times on pin 12 (which is constantly calling the "loop" function) and then when you press the volume down button for example, the 51Kohm and then the 25Kohm are in parallel, so equal to 17Kohm, which is no function. Using resistors, you need to have them all connected via push buttons. The gaps between the songs is a limitation of the DFmini. This is the time it takes the unit to access the files from the SD card and start playing. So, you can't "loop all" and have a continuous sound track from various stored files (which would be nice for certain applications).

[@kevinmithnick9993]

how much is the gap?

[@MuhammadBilal-qp2kp]

Brother, I want to use a potentiometer to control the next/previous song. or any other rotating method. can I do this with this module?

[@FadsToObsessions]

I think you could, using the AD key connection method, where pin 12 (ADKEY1) is connected via suitable resistor to ground via a push button, see kzbin.info/www/bejne/nX7ZY6t9fbGLmrc If you replace all the resistors with a single potentiometer (a 50K may be enough) and the pot wiper to ground via a push button. Then when the pot is set to a specific value, and the button pressed, you would get that particular function. However, the pot by itself (without the push button to ground) would not work.

[@bronsonleiro]

Fantastic tutorial. Would it be possible to connect multiple df players to one arduino, and have each connected to their own speaker? I am attempting to make an instrument that plays a noise by the push of a button and each button/noise would have its own speaker. Thanks in advance.

[@FadsToObsessions]

You would need a multiplexer (like HEF4051) so that a single arduino (with the TX pin through a voltage divider) could then control multiple DFPlayer's (the HEF4051 would allow up to 8 to be separately controlled). Each DFplayer would have its own speaker. The push button for each DFplayer I suppose would be connected to the ADKEY1 pin via a 33K resistor (if I understand what you a trying to do). You could maybe do this without even using the Arduino, if you don't need the arduino to select tracks, change volume etc.

[@bronsonleiro]

@@FadsToObsessions I appreciate the response. Would an L293DNE or a 74HC595 have the same function? Also, through the ADKEY1 pin, what would I name the mp3 file if I was not going to use an Arduino? And do you have any troubleshooting tips for when the df player won't respond with its blue LED, but the speaker is still receiving power?

[@FadsToObsessions]

Unfortunately, neither the L293DNE (a H-Bridge driver) or a 74HC595 (a shift register) can be used in place of a HEF4051 (a multiplexer). The mp3 files should be named 0001.mp3, 0002.mp3 etc (see 4:50 in the video). The blue LED not working is a bad sign. Recommend double checking DFplayer is Ok by hooking up the basic standalone circuit (see 1:25 in the video), check and double check your wiring and power supply, and then see if it works (see 2:40 in the video). At 2:40 in the video, it shows that when powered on, nothing happens (blue LED not lit) until you press one of the play buttons. Good luck.

[@bronsonleiro]

​@@FadsToObsessions Thank you for your time. I was able to use no resistor to utilize the segment 1 command on ADKEY1, as well as the segment 5 command on ADKEY2 . My main issue was a proper power supply, as I fried one module, and the rest had insufficient power. This was corrected through the use of a desktop power supply.

Thanks for commenting back on your success/trouble shooting - will be perhaps helpful to others. Cheers.

[@lamduy3663]

I can only get 4 segments, I can't use resistors to get 5 or more segments on ADKEY1 and ADKEY2. Please help. Thanks!

[@FadsToObsessions]

Double check your resistor values (and connections to pins/ground etc), double check you have named the "segments" (which are just the files on the SD card) correctly (see 04:40 in the video), that's the best I can offer at the moment. Over the next few days, I'll recreate the circuit with more than four "segments" using resistors/buttons and post the results.

What's the maximum ohm of the speaker? Sorry for the newbie question.

I've used both 8 ohm and 16 ohm speakers, the datasheet states "drive speaker less than 3W" - the speaker in the video is 16 ohm

[@kylenorman6179]

HELP! I copied your code line for line, but it won't actually adjust the volume. The other features work (next/previous and play/pause). What's going wrong?

[@FadsToObsessions]

Since the play/pause etc are working, therefore your code would appear correct and is successfully connected to the MP3 player, sending commands via the serial port etc. The same function is used to send all the commands, so in the first instance maybe a hardware problem. You could check that the variable theVolume is initialised properly (int theVolume = 15;) before the main loop, as with my modules, the default at power-up appears to be maximum volume. On power-up, if your module isn't playing very loudly, again indicting hardware and/or power problem. You could try hooking it up with the resistor ladder (~ 4:30 in the video) and checking that the volume can be adjusted with push buttons - this would check that the module is working ok.

[@dapromasta]

Hey I am trying to use the DFplayer mini as a standalone(powering it now with an arduino), because I want to keep my entire project as small as possible. However when my mp3 file hits a loud note my speaker (1 watt, 8 ohm) simply just stops. do you have any tips?

[@FadsToObsessions]

The voltage regulator on an arduino (well at least with a Uno or similar) is only ~1A and if powered from USB, you should limit total max draw to be only 500mA. From www.arduino.cc/en/Main/arduinoBoardUno> "The Arduino/Genuino Uno has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. ... If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed." So, unfortunately, you will probably need to look at providing a separate supply for the speaker.

[@dapromasta]

you need to use command 0F "specify playback of a folder" (see table 3.2.1 of the datasheet page 4). This command has two "parameters" the "folder" and the "track" (both folders and tracks need to follow the naming convention using "numbers" for the track and folder names). Section 3.3.4 shows the command and examples. You must specify both the folder and the file name to target a track.

can this play a single file on power up somehow? or does it need a micrcontroller? -- thanks

The DFPlayer does not have "play file on power-up" functionality as far as I know. So, a microcontroller as you say, or perhaps some external circuitry (maybe a RC time delay with a Schmitt buffer to trigger low the ADKEY1 (pin 12) to play track 1) will be needed. Microcontroller likely easiest, getting an active low trigger on start-up with "passive" components possibly "tricky" depending how the DFPlayer reacts on power-up.

I'm assuming you have the other functions working, so basic connections etc OK otherwise. First recommendation would be checking the resistor values, which for the loop all function, the datasheet states 51K ohm - although I found the value doesn't need to be "exact" but fairly "close" (so maybe you are not close enough??), secondly, perhaps check the naming of your files on the SD card - need to adhere the datasheet naming format, as maybe this could be causing interference.

@@FadsToObsessions thanks for the reply! Where should I put the 51k resistor?

In the video, this is the short horizontal purple wire on the bottom, then through the vertical orange etc. I did not have 51K, so used a 47K and a 3.9K together in series.

[@FadsToObsessions]

@Nerya Oh, in that case, after hooking-up the nano (see 7:50 in the video for schematic etc if you haven't done this already) will need to add some code (see 9:30 in the video). The datasheet page 4 section 3.2 lists the various commands available. In the example code in the video, I have a function called "do_MP3_Cmd()" which can be used to send the desired command. For loop all, try using do_MP3_Cmd(0x11,0,1) to start repeat all playback and do_MP3_Cmd(0x11,0,0) if you want to stop repeat all playback.
