depends on how loud (dB) you want it, then you'll be able to sort your requirements of the speaker (passive or active) and the rattling, you could probably do a quick fbd, and design a weight attached to an arm on a non-continuous positional servo to keep the COM low, but able to shift it to mimic the rattling just make sure you check the torque specs to stop slipping. That way you can control the rattling better and sync it with the audio. When selecting your power supply, just make sure you meet the voltage requirements for your components and set an arbitrary time you want this device to last. (Longer, the more bulky the battery generally). Optionally for the motor, you could do a motor attached a wheel with a lob-sided weight and derive a sine function for the movement to control its speed and etc. :)

Hi, What capacitor do you add to the circuit? Do you have the electric diagram file? Thank you!

@d.g.m.04

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

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?

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.

@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.

Does anyone know if the capacitor on the 5V and ground necessary?

@JustBaselmansYT

24 күн бұрын

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!

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 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.

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?

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.

@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.

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
