Absolutely necessary? Definitely not. Can it help if the audio quality sucks? Yes. Also it depends a bit on what kind of 5V source you are using. I would suggest just try it out. Good luck!

@DatFunnyPerson control with uart and create a while function for the button being held and "else if" maybe. And have it play the sound and read if the player is playing or not. From there I would either pause or stop when released on the "else" function

@@lamboking8able that's cool but it's like I'm reading Chinese. I'm a real noob and can't code at all haha. I was hoping someone had a code ready or something

@DatFunnyPerson 😂😂 believe it or not I'm a noob as well. But I'm starting to understand it little by little. More so reading code rather than write ot. I recommend (if you think it will help) using copilot or chatgpt. Ask it a thousand questions. It'll help you understand it. But the dfplayer has a "playing" pin. I would say use a (read) function on that pin to any pin on the esp32. And say something like if(playButton == high) {If(dfActive == high){ Play(sound1); } } Now again. I'm a noob. I haven't tested this. I'm sure there's a few syntax errors but this is something you might can install into the sample code. I would also recommend asking chatgpt and or copilot to explain it to you. The sample code. It has helped me be able to read it a little better until I can do it on my own.

If you look for 4ohm 3watt speaker on Aliexpress you should be able to find them. Good luck!

Oh, I'm so dumb, I had no clue this channel had much to do with those robots, but vector is literally in his pfp

Haha insane you noticed and yes, love working with the little guy and am very sad he is currently not really supported anymore :'(

​@@JustBaselmansYTyeah, I found that out the hard way :( The solution is WirePod. It's a free alternative to the servers (which are down). You'll have to Google to find it since my comment with the link got held for review or something, but it's on GitHub. I hope that helps!

Did you ever get an answer for this, here or anywhere else. I'm wondering the same thing, also have a time critical projekt.

@DalaFilmprod YES! I find online about a 0.03 communication time from esp32 to dfplayer. I switched to the dfplayer pro, but I would say in experience that's about as fast as it starts. Near instant so definitely go for it.

Fyi I'm using uart1 (which I moved around to use) to communicate with it.

Can you maybe further explain the problem? These functionalities should be able to be added to most arduino projects

@@JustBaselmansYT I got it figured out now, btw I was meaning like only use arduino uno and not the bread board, now no need I got it figured out, thx btw, thx cuz I learned how to put the wires

Format it in the sd card settings from windows by right clicking the card in your files.

Danku danku😂

Hey, hope it is now working! Enjoy the project

yeah it’s working now thnaks for the video

They are from AliExpress search for LED button

It's an old laptop speaker however every 3 watt speaker should work

@@JustBaselmansYT Thank you so much!

(and also, why are you showing 2 type of buttons and you just pick the smaller ?)

There is a new video coming soon on this but it is a lipo battery connected through a tp4056 charger board

Because I got both and already have one with the other button ;)

By following the steps in the video :) I'm not sure if I understand the question

Exactly! And why? 🤔🤔

@@livetohash6152 ruclips.net/video/u40kX1DYKdA/видео.html

if your sd card is more than 32 gigabytes (yeah i know that’s overkill for most projects) an application is needed to format 64gig and beyond to fat32

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

@cadillacescalade5428 if it didn't work, I'm also using ir sensors, and I used uart1 which I had to move to a new location on the board

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.

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

@@totallyistimmy thanks!

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.

You need an ultrasonic sensor (to measure distance), an arduino (does not matter which one) and something to play sound. Any of these 3 options can do and I also have a few other videos on ways to play audio using arduino.

@@JustBaselmansYT Oh ok. I'll see it later! And thanks by the way!

Chip? Do you mean clip/hinge because then it's called a hidden barrel hinge

The capacitor is probably something like 100uF to 1000uF and it's there to smoothen the voltage if it varies on sudden changes

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

www.reddit.com/r/arduino/comments/5uweoz/how_can_i_generate_random_numbers_without/

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

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.
