That's so nice to hear! Good luck with your project ;)

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

The DAC_R and DAC_L on the DFPlayer can be used for this purpose!

circuitdigest.com/microcontroller-projects/interfacing-ir-sensor-module-with-arduino 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

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 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

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

capacitor, it’s not necessary it’s just there to maintain a smooth signal

@@totallyistimmy thanks!

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.

that doesnt help me because i cant code anything. im a noob. all i can do is copy and paste@@JustBaselmansYT
