Audio modules for electronics project

In this video, I'm going to demonstrate various common audio modules - devices you can use to add music or sound effects to your Halloween scare props, escape rooms, model railways, or any other electronics projects!
Particularly, I'll be comparing the following:
DF Player Mini, Catalex Serial MP3 Player, (including the YX5200, YX6300, MH-ET LIVE MH2024K and AA20HF "variants"), DY-SV17F, DY-SV5W, DY-SV8F, DY-HV8F, DY-HV20T
Some of these devices can be controlled by code sent from an Arduino, ESP32, or Raspberry Pi, whereas others can be used as a completely standalone device - requiring you only to connect a power supply and speaker. Playback of different sounds can then be controlled by pressing different buttons (or any other inputs), which makes them ideal for use in an interactive museum exhibit or other installation.
Now, it's going to be impossible for me to convey the volume or quality of these modules in a video.... they're all just going to sound like the speakers you're currently listening on at the volume level you've set (possibly a little bit more distorted due to my microphone!). So, I'm going to concentrate on demonstrating these other features instead:
- how to wire them correctly to minimise static noise, clicks, etc. and prevent erratic behaviour during playback
- how to prepare and store audio data (using, e.g. using Audacity to normalise and trim audio files, and DriveSort to ensure that track 00004.mp3 really corresponds to track 4 on the SD card www.anerty.net/software/file/D... )
- comparing ease-of-use; some devices can be wired directly to the GPIO pins of a 3.3V or 5V microprocessor, whereas others need external components such as resistors or capacitors
- testing audio latency between flash memory and SD card devices

One thing that I think is worth mentioning, is that the WAV Trigger lets you play up to 14 audio tracks from an SD card AT THE SAME TIME. This is extremely useful and I have not found a suitable alternative that can do the same thing.

@PlayfulTechnology 3 ай бұрын

That is true; whenever I've needed multitracked samples I tend to just trigger them off seperate devices (e.g. 4x DY-SV17F wired to the same ESP32), which works out cheaper unless you really need a lot of polyphony.

Thanks for that fun and enlightening video. I've just started messing around with audio stuff (via I2S), and have an ESP32 MCU and a Sparkfun WM8960 breakout board. So far, I can say that the WM9060 is complicated as heck, but you can probably do almost anything you can imagine with it (but maybe I have a limited imagination). Between the "Analog in" to "I2S out" section and the "I2S in" to "Analog out", and combining with Bluetooth and/or Wi-Fi, I imagine there's not much you cannot do with this breakout board. I'm still trying to figure out, when you read or write the I2S interface, how the code can discriminate between left and right channels in the buffer memory. Great fun, thanks again!

Hi Alastair, thank you for your videos. I have been watching your projects for years, as you are the only person on youtube that handles some of the concepts needed for the weird things that I come up with and try to learn how to build. Recently I was researching this very topic. I found out you can play audio files from an ESP32 by wiring it directly to an sd card (easiest setup is to use a microsd and solder the wires to a sd to microsd adapter) and to a speaker. I found this setup to be the minimal option to be able to play random audio files with minimum number of items and space. I think there might be a way by using logic gates, a timer and a standalone dfplayer but if possible it would be quite more complex. I am sharing this option because I usually have very little room available, and I almost go mad every time I have to face the inconsistency of the dfplayer.

@PlayfulTechnology 10 ай бұрын

Thanks for the comment! You're absolutely right - you can play back audio files using only the ESP32 hardware (in fact, you can even do this on an Arduino [at very low bitrate] using something like the TMRPCM library: github.com/TMRh20/TMRpcm). I didn't mention this as a viable solution though, because it tends to occupy a large amount of the limited resources available on an embedded chip, both in terms of processor and memory usage. So, if you try to get your sketch to do anything else in addition to playing back audio (e.g. polling button input, reading a sensor, or applying any controller logic) you quickly run into timing issues and playback becomes unacceptably choppy. That's why generally I'd recommend offloading responsibility for audio functions to a dedicated audio chip like those mentioned in the video, and all the ESP32 has to do is issue a few simple byte commands.

Automatic arati player. What I need is a music player play audio file from SD card on a perticular time. Example: 1. Player should turn on at 06:00 am play audio track 1 for 26 minutes 44 seconds and turn off. 2. Turn on at 12:00 pm play audio track 2 for 19 minutes 55 seconds and turn off. 3. Turn on at 06:00 pm play audio track 3 for 22 minutes 12 seconds and turn off. 4. Turn on at 09:00 pm play audio track 4 for 16 minutes 11 seconds and turn off. Note: I am doing it with smart switch with scenes. Which turning on my Ahuja 250 amplifier and multimedia kit with USB TF AUX & BT. Timmer working fine but managing seconds are a problem here. And changing audio track every day is not what am looking for. Anyways managing adding blank audio to match the timing. I'm looking for fully automation. It's for a temple. Audio module with Arduino is a option here but I'm not a programmer. Is there any pre built device available please let me know? If anyone like to help me with this most welcome. I can offer a like a cup of coffee. Thanks in advance.

I really appreciate this video. I am a senior, with no electrical engineering background. I make simple animated props for a yearly haunted house fund raiser for a 150 year old lighthouse. I am currently trying to add sound to one of my props. With the help of your video, I wired a DY-HV8F sound card with 5 different sounds, triggered by small push buttons. When I use an amplified external speaker, it works great. When I use a 4ohm 3w speaker, that I want to put in the creature’s head, I can barely hear the sound. I’ve tried adjusting the potentiometer, but it doesn’t have any effect. What am I doing wrong?

Excellent video. Having spent a lot of time experimenting with Catalex, DF Player Mini, and clones ... Chip numbers: I've mostly seen XY5300 and a few XY5200. I haven't seen XY6300 anywhere. Even for chips with the same number, there seem to be various revisions in circulation, each with their own set of bugs. DF Player Mini: Your current estimates for basic playing and file loading are higher than what I've measured (27 mA playing audio to DAC output with the amplifier disabled, slightly higher if playing from USB flash drive). When not using the amplifier, I've never had problems powering it from an Arduino Pro Mini's regulator, even when the Pro Mini is providing power to several other components. Using a diode to drop the VCC supply and a capacitor to smooth things out makes a lot of sense. I'll do that in the future for sure. For the serial line, I use two resistors arranged as a voltage divider to drop the 5V output to right around 3.3V at the player's RX pin. Catalex: The Catalex draws a little less current than the DF Player Mini. The essential commands are largely compatible with the DF Player Mini, but there are subtle differences in behavior when using the serial interface. For example a DF Player Mini will clamp the volume level to a maximum of 30, but a Catalex lets you set a higher level (like 40) and will even confirm that it is at the higher level even though it appears to look at only the lowest five bits, giving it an effective range of 0-31. Catalex will let you change the equalizer setting during playback, but on the DF Player Mini that'll stop playback. Catalex doesn't implement some of the more esoteric commands, and it can return bogus values for some status queries. File Index versus Track Number: The basic Play command does indeed work by the file's index in the FAT regardless of how the file is named. Likewise, Next Track and Previous Track simply step by file index. The Playlist command is documented to use file indexes, but I haven't been able to confirm because none of the devices I've tried seem to support it. But there are other commands (Play From Folder, Play from "MP3" Folder, Insert from "ADVERT" Folder, and Play From Big Folder) that actually require the file name to begin with the track number (in decimal using an appropriate number of digits encoded in ASCII).

My experience with the DFplayer mini is the same I've never yet found one that performs 100% of the functions in the spec.But generally they are good enough and cheap. I would be interested to know how you would incorporate a variable volume control as this is often needed though

@PlayfulTechnology 10 ай бұрын

The DFPlayer has software-based volume control. So, if you're controlling it via the serial connection, you can issue a command like myDFPlayer.volume(10); to vary the volume supplying a value from 0 (min volume) to 30 (max volume). If you're using it as a standalone device you'll need a hardware-based volume control instead: your first instinct might be to put a rotary potentiometer into the speaker output, but this will change the impedance between the amplifier and the speaker. The "correct" solution would be to use an L-Pad attenuator instead, like one of these: cpc.farnell.com/c/pads/l-pad

This information was exceptionally useful, thank you for the great work in setting this up. I'm planning a hardware soundboard project, and although I'm well versed at scripting, this will be my first "from-scratch" electronics project, as well as my first foray into Python. The tricky part of this project is that the hardware buttons wont trigger a single sound file, but a random one within a specific directory. So I'm leaning towards the DY-SV5W board in serial mode, with Python code to choose a random index to send to the audio board when a given button is pressed. However, I'm unsure of how to know if the max number of files on the MicroSD card from the arduino to be sure the random index sent is within range of the amount of files in a given directory on the card. For that matter, can i even use directories on the card if the Arduino is just sending a single file index number? Is there a better recommendation for my project idea? Requirements: - i can drag and drop MP3 and WAV files to the MicroSD card like ../dir1/sound1.mp3, ../dir2/sound53.wav - i can press button1 to play ../dir1/[randomfile] or button2 to play ../dir2/[randomfile] With my amateur knowledge, i would expect that the file storage probably needs to be accessible on the board doing the logic, which would be the Arduino in this example, is that accurate? Furthermore, is there an Arduino board that can do all this on it's own without needing a secondary audio board like the ones on your video? I appreciate patience, as this is my first dive into the world of microprocessor boards, aside from casual RPi tinker projects.

Hey Alastair, Just looking at the diagram you made for the DY-SV17F but the 5V line from the player is running to VIN on the arduino. Is this correct? I would have expected that you would want to connect it to the 5v pin of the arduino so you can power it from there

Great video as always! WRT DY-SV17F, what is the purpose of the three pull-up/down resistors? Since there is only a single connection to each pin, it seems to me those pins could be directly connected to +3.3V or GND as appropriate. I've only needed them to ensure an input does not float in the absence of an input signal.

@PlayfulTechnology 9 ай бұрын

I'm not entirely sure why the inline resistors are necessary - like you say, to set a logic signal of HIGH/LOW, you would think you could directly connect them to 3.3V/GND, but according to the documentation the resistors are necessary in both cases. This is also the way that the DIP switches are implemented in the 5W/8F boards. You can try without, but be warned in case you get funky behaviour!

When I switch on the first + lead to ACC, I want it to activate the "Welcome back Sir". that switch will remain on providing power to ACC. then When I switch the Coil Lead, I want a "Ready to start Sir". Possibly a few others, but is it stable to trigger multiple soundbites once with an always on switch? Did that make sense haha

Had the similar issue with DY-SV17F with builtin memory, in my case it took 500ms to to initiate audio.

@PlayfulTechnology 10 ай бұрын

Was that playing a MP3 file or a WAV file? 500ms is very slow :( One possible explanation for the long delay is that an MP3 file is compressed, and the chip does not have a very efficient decompression algorithm. Playing a WAV file should be more responsive, as that's uncompressed raw audio that can be read and immediately streamed. The downside of that is that it's a much larger filesize, which is tricky when you've only got 4Mb storage to play with...

I've not experienced that problem myself. What setting did you push the DIP switches to?

@jonathanlevin7660 4 ай бұрын

@@PlayfulTechnology It was a while ago, but I think I literally tried all permutations after getting frustrated. Pulling the pins either high or low just did not trigger the tracks (but in UART MOde I was able to play them by index, and in the default MP3 mode I was able to skip between them, all with the same SD card). Where did you buy your modules from? Perhaps Ill try one

@@jonathanlevin7660 I've bought several batches from different vendors on AliExpress - I do normally use them in UART mode anyway, but occassionally use them in trigger mode and not noticed any problem - you just need to have the filenames saved appropriately on the SD card and the DIP switches set correctly.

@@PlayfulTechnology a couple months later I finally figured out the issue.. As you said the filenames have to be correct, I had "0001.mp3" and the module needs specifically 5-digit names "00001.mp3"... The tutorials I saw claimed that the modules use the FAT index, so what matters is the order in which you copy them over. This is untrue. One would assume even if not at least it would sort alphabetically- but nope, specifically 5 digit numbers with postfix `.mp3`. Most "datasheets" for these also fail to mention this, but oh well! once known it's a very solvable issue

I am going to use a DFRobot Min iMp3 player on my next project with an Arduino R4, I'm going to use a breadboard power supply to power the device independently using the 3.3v option, do you think this will be okay?

Hi. Great video! I would liketo show the active file on an lcd. So do you know any such module which allows to read the filename from the storage device? Or let you stream the data to it so you can access the files via an sdmodule?

@PlayfulTechnology 2 ай бұрын

These cheap audio modules only have a basic access to the filesystem of the SD card, and unfortunately don't expose it to allow any queries from the microprocessor either. To do that, I'd use a standalone SD card and then stream the data to an audio chip using I2S, but that's quite a lot more involved.

Really struggling with a DY-HV20T at the moment. I got it to work once (although it played 3 tracks as if it were skipping to next) using a test sd card I had. I removed the sd card, changed the files to the one I wanted (playing an explosion only) and now it's lifeless. Did you find an documentation on the dip switches and modes, other than what's on the Aliexpress listings? Thanks, Patreon Steve

hi i have been looking for a small mp3 player but i do absolutely need the output to be stereo i have tried the df robot mini player board only to find it only outputs a mono audio i confirmed this by tracing the dac L and dac R pins they ultimately go to the same pin on the mp3 chip on the board i was looking at the other boards you show in the video but i cannot find any schematic diagrams or other specifications and or pinouts of the ic so i could confirm that those boards are indeed stereo via the 3.5mm jack i am not bothered about any on-board amplification as this is done elsewhere in the project all i want is a simple to control via a serial connection MP3 player that outputs a stereo audio. Can any one confirm if any one of these boards are stereo?

Amazing again i just love watching your channel, i have a question please, i am currently building an animatronic Parrot using an esp32 and controlling it with a playstation 3 controller. i dont know if you have used esp32 arduino in the fashion im hoping to do, i just love the idea of being able to speak through a microphone and the parrots mouth would open and close using servos as close to my voice speaking as possible. do you think this is something that i could possibly add to what i have already done with the parrot. Many thanks Alistair i hope you can answer my question. I am building it with 6 chans, with 6 servos even though that is a nightmare coding, so i am currently looking for an arduino coder that maybe able to put the sketch together (paid of course) for me if you know anyone.

You should be able to find distributors easily by searching for any of the model numbers. My parts drawer has hundreds of these modules which I've bought from all sorts of suppliers - I didn't include specific purchase links, partly as I don't want to be seen to be recommending any particular supplier, but also partly because I couldn't honestly tell you exactly which unit came from where!
