Great video plus code is super helpful, appreciate!
awesome this video helped me out in a recent project :D
That's so nice to hear! Good luck with your project ;)
Hi, What capacitor do you add to the circuit? Do you have the electric diagram file? Thank you!
Hey i want to make a pokemon ball vibrate and make the pokemon captured sound. Which power speaker shoild i buy? Which microcontroller as it needs to be small and which type and how many batteries would i need?
I happen to be working on a few videos about a 3D-printed realistic PokeBall. I will also be working on electronics for sound and the signature shake so more on this topic soon😄
@JustBaselmansYT so you're my competition 😏 I actually have all the components and I tried your code for the pokemon ball but the code you gave didn't work for the dfplayer to play the pokemone sound
ive seen the other video and this is module is good
Absolute legende ben je!
Danku danku😂
I need to play the RAW sound by the Arduino mic and play with it's speaker?
Great video! I’m trying to do led effects and sounds effects working together. I’ve got it working. But the df player is so slow. I press the button and my led strip fades color instantly and is almost done before the df player plays my file… is this normal behavior for the player?
You realise you can format the thing from Windows? Like you don't need an app. TBH I'm not even too sure why those formatting apps even exist?
what would you say is the latency between pressing the button and the sound starting. Currently I'm using an esp32 with an I2S and my latency is between 0.2 to 0.3 seconds with human error between that. I need it to be less than 0.15 seconds as I'm synching a gunshot sound with a trigger pull.
i cant find the library u used?
I 'am new to coding sooo can someone help me make buttons for all the serial monitor command's pleases
Hi, I am wanting to use DF mini player with a sketch I have already how would I incorporate the DF-Mini into my sketch ?
Also I have a IR sensor as well that activates my sketch I'm wanting sound and for it to stop playing when ir sensor is uncovered.

You can use this code but instead of turning an LED on and off you can use mp3_stop() and mp3_play()
@JustBaselmansYT ok Kool thank You
Is there any way to output the signal to a 3.5mm jack? so you can control a external speaker?
The DAC_R and DAC_L on the DFPlayer can be used for this purpose!
what capacitor did you use for the circuit?
Exactly! And why? 🤔🤔

I already installed that apps, but it says, "Cannot format write protected card". How to solve this problem?
Format it in the sd card settings from windows by right clicking the card in your files.
Anyone have the error where arduino is stuck building a sketch and unreadable symbols are printed in the serial monitor?
Figured out it was the Baud rate. Also, the TX and RX are reversed in the code. Where it says the value for RX is actually TX and TX is really RX.
ya I have that same error how do I fix it
@plantor0728 make sure the number in Serial.begin() matches your serial monitor. Default in serial.begin is 115200. While your arduino is plugged in, go to serial monitor and look to the right side of the screen. You'll see a drop down that says some number, probably 9600, and baud. Adjust that to match 115200.
@@ZF0317 thanks man, it’s not spitting out mystery symbols now
No problem @plantor0728! Let me know if other questions come up.
Hi! I set my arduino up exactly the same way you did (with the exception of using an Arduino R4 WiFi) and the readout in my serial output is the following over and over:
Not initialized:
1. Check the DFPlayer Mini connections
2. Insert an SD card
I tried swapping out my R4 for my R3 and I got the same result. I've also isolated all of my components and have tried three different DFPlayer Minis. I'm using a 3-watt, 8-ohm speaker, and I'm using a Mac. Any ideas? I'm at a complete loss at this point.
Hi Vijakarina can you try uploading the "GetStarted" sketch that comes with the DFRobotDFPlayerMini library? Please let me know if it does work with that sketch, good luck!
@@JustBaselmansYT This is what I'm getting when I run their GetStarted sketch:
DFRobot DFPlayer Mini Demo
Initializing DFPlayer ... (May take 3~5 seconds)
Unable to begin:
1.Please recheck the connection!
2.Please insert the SD card!
@@vijakarina and you are using an external 5V power supply? Because if this is the case and you did check all your connections and check if there are indeed songs on the SD card (which is smaller or equal to 32GB) than in my experience pushing the reset button a few times should be enough to get it working.
@@JustBaselmansYT yeah, unfortunately I've done all of that. I've also gone through and removed the hidden files from the SD card that the macOS loads onto it. I've tried different 32GB microSD cards, I've reformatted them all to FAT32. And I've pressed the reset button a bunch of times, all with the same result. Thanks for your quick responses!
@vijakarina I am sorry that it does not work for you :/ but I also do not know what to try expect for a different tutorial with s different circuit and different library
What happens if i dont use a resistor?
I think you will fry the board because it's based off of 3.3v rather than 5. If using esp32 you don't need it I HEARD. Please look more into it.
it is a pity that you skipped over the last part of button installation so quickly. i had to playback several times to try and see what you were typing to add the button command. code now gives error 'pinmode' was not declared in this scope.
Put the following 4 lines of code at the top of you void loop, good luck!:
if (digitalRead(2) == LOW) {
Serial.println("now playing track 1");
myDFPlayer.play(1);
}
Okay thank you, your video & instruction is very helpful. I was struggling a lot to get buttons to play tracks. I am making a customer queue manager with 6 pay points, each with a button to press and play sound 'next customer to till 1,2,3..." etc. I have added this to your code and the 6 buttons ( d2 - d7 on arduino uno) are all executing perfectly. void loop() {
//instruction for button on Digital input 2
if (digitalRead(2) == LOW) { //reading of digital 2
Serial.println("now playing track 1"); // serial monitor line display
myDFPlayer.play(1); // track number/name to play
delay(1000); //debounce delay
}
if (digitalRead(3) == LOW) {
Serial.println("now playing track 2");
myDFPlayer.play(2);
delay(1000);
}
if (digitalRead(4) == LOW) {
Serial.println("now playing track 3");
myDFPlayer.play(3);
delay(1000);
}
if (digitalRead(5) == LOW) {
Serial.println("now playing track 4");
myDFPlayer.play(4);
delay(1000);
}
if (digitalRead(6) == LOW) {
Serial.println("now playing track 5");
myDFPlayer.play(5);
delay(1000);
}
if (digitalRead(7) == LOW) {
Serial.println("now playing track 6");
myDFPlayer.play(6);
delay(1000);
} I would however like to tweak the code more to have the button presses form a digital queue so that if for example: Till 1 presses button 1 and track 1 plays. If then button 2 is pressed while track 1 is still playing it must not interrupt or stop track 1 from playing. Track 2 must queue and play as soon as track 1 is finished and so on. Do you have any advice please? Thank you
Pinmode error usually means you did not declare the pin as input or output in the setup section.
What was the external power supplies voltage
5V direct current
Is it ok with 9v
3.2 ~ 5V is stated in the datasheet of the dfplayer mini so 9V is not recommended. Not sure what will happen but if you are worried about damaging it, then I would not try it.
@@JustBaselmansYT btw what kind of resister are u using
this may sound dumb buuut what is that green thing.
capacitor, it’s not necessary it’s just there to maintain a smooth signal
