All you need for WLED Sound Reactive Matrix using a Digital MEMs I2C Microphone

[@3ATIVE]

🎶Don't forget: All the tools and "Stuff" I use can be found in the Video description via the Amazon Shop Link.

[@ChunkySteveo]

Is there a link to the mic?

[@ChunkySteveo]

Ignore my lazyness.... click the Amazon Link!!! Haha

[@MikeSims70]

WOW ... and without needing to write any code ... awesome!

[@3ATIVE]

I know right - We LOVE WLED.

[@hernandezyo1971]

¡Antes que nada Gracias! como le haria para poner directo el audio con un plug 3.5 GY-PCM512 I2S IIS en lugar del microfono digital?

[@3ATIVE]

*OMG, muchas gracias por el "Super Chat" - Es muy apreciado.* Lo siento, pero esa placa es un convertidor digital > analógico. Necesita un conversor analógico > digital. Yo también estoy buscando uno para mí. Sin embargo, no he encontrado uno. Cuando lo haga, publicaré un tutorial.

[@michaelo2l]

I have build several ESP32 spectrum analyzers but this is my new go to.... great video, many thanks... Is there a version that uses direct audio without the need for the mic?

[@3ATIVE]

I have some running here too - Such a great effect. All mine are Mic-ed, I'm still looking for a suitable (A.K.A. Cheap) Analogue to Digital Converter myself. - I mean there are plenty available but nothing I could recommend.

[@kristupasdudenas4567]

I was about to write my own shyt code, but then I saw Ur vid. You saved me from alot of stuff. Idk Arduino code lol

[@3ATIVE]

Thank you, @kristupasdudenas4567! I'm thrilled I could help. Feel free to reach out for any more assistance. Happy coding! 😊

[@theaustindude]

I noticed you left the "LR" pin on the mic unwired. The diagrams I've seen show that going to ground. Any reason you didn't connect it to ground and any issues as a result?

[@3ATIVE]

From what I saw, that wasn't needed and as you can see it worked without it. :)

[@theaustindude]

@@3ATIVE Got it! The wled documentation specifically says to NOT leave it disconnected, so I was curious. Not using it, simplifies the soldering for sure!

[@3ATIVE]

Oh yeah.... I never read that WLED post. Here's what I found on the INMP441 Datasheet: "Left/Right Channel Select. When set low, the microphone outputs its signal in the left channel of the I²S frame. When set high, the microphone outputs its signal in the right channel. "

[@Debendram9]

I have the same INMP441 digital mic attached and same settings applied but the geq like sound reactive presets are every time flashing with out any sound (the effects are not reactive to sound) even after all same setting like yours

[@3ATIVE]

Sorry to hear that, clearly it does work. I would say: Check your wiring and settings again.

going to build a festival totem with this matrix

[@3ATIVE]

A Sound Reactive Totem !! - That sounds cool. 👍👍

[@LAGASTEST]

Great video! Can you use WLED to program led strips on a sofware like LEDedit or JINx?

[@3ATIVE]

Thank you, I'm glad you liked it. Yes, once WELD is setup you can use JINx quite easily, I have it setup here atm - I haven't tried LEDedit thou. Here's me testing JINx running in to WLED: instagram.com/p/CsH2FskNTQC/

[@haj5856]

Really useful video, thanks

[@3ATIVE]

Glad it was helpful!

[@o0OMouseO0o]

I had no idea WLED was so versatile.

[@3ATIVE]

Yeah, it's pretty cool. Did you see my previous tutorial, Scrolling Text?

[@john_beardon]

Nice one Dave - thanks! Still haven't ordered the bits 🤣

[@JanK001]

Good morning great videos Question: Which software do I have to flash for the esp8266 and on which pins do I have to solder the microphone on the esp8266? Kind regards

[@3ATIVE]

Guten Morgen Herr Jan, I use "ESPHome Flasher": github.com/esphome/esphome-flasher/releases As for the pins on an ESP8266 - I have not tested on that but, the Mic is digital and my guess is you can choose any that are not boot pins.

[@JanK001]

@@3ATIVE Good morning, it did not work with the esp8266. I flashed successfully (WLEDMM_0.14.0-b1.13_esp8266_4MB_min.bin), but nothing is displayed in the configurations regarding sound settings. strange... the esp8266 chip maybe too old? does anyone have an idea whether I could try another firmware, if so which one? Important for esp8266 and led matrix with sound reactive. Regards Jan

[@nyetloki]

​@@JanK001the 8266 sound firmware is no longer provided. You need a esp32 for the recent sound firmware. Unless you download old copies of the not great 8266 sound version

[@JanK001]

@@nyetloki it worked, but only with the esp32. Kind regards

[@andrewelliott7830]

Good day legend. Have you made any progress finding a good diffuser? i've managed to get far enough that its time to deploy but im struggling to find a nice finish for the matrix.

[@3ATIVE]

And a good day to you too fella. No, mine are still 'raw' on the desk. I did look at some grease-proof paper: amzn.to/3nCeD1i Which I planned to adhere to some black tinted perspex: amzn.to/42akNVs - But, never went any further.

[@drelectronics13]

I just love it 😍 and way u explain

[@3ATIVE]

Thank you so much 😀 I hope it was helpful for you too.

[@ferinoch]

What board did you use for this? I looked at the amazon link you mentioned, but all the boards listed are ESP8266 and don't seem to match up with what you show in the video.

[@3ATIVE]

You are right, they must have changed the listing(s) - Here is a new link: amzn.to/3yqElLE

[@ferinoch]

@@3ATIVE much appreciated, thank you! And thank you for this tutorial, I tried it with a diff board and had to muck about some to make it work, but I got it working and am quite happy with it.

[@Nobbi_TheRock]

Year and again a nice Video. How about 2 LED Panel? Will it work? .. Have a nice Day

[@3ATIVE]

Thank you. Yes 2 panels... There are two options: 1. Connect one to the other - giving you one that is 64x8 2. Connect the 2nd to another GPIO pin - giving two (independent) 32x8 displays.

[@3ATIVE]

Ooo, option 3: Connect one to the other and configure them to be 32x16

[@jupiterjs031]

How do I connect matrix modules? Do I just need to connect SCL and SDA?

What "matrix modules" do you mean?

[@Koi-Koi-Koi]

hi do i have to connect my esp32 wled with the 3 pins L/R, WS and SCK? or is it enough to connect onbly Vcc, GND and Out as many users do with a pin micro?

[@3ATIVE]

Hi, No you don't have to connect all the pins but, if you want it to work as I've shown you will. 😉

[@delboytrotter7902]

Are the matrix effect and pong game part of the software, or do i have to do a bunch of jiggery pokery to get them ?

[@3ATIVE]

They were both included in the original download from MoonModules.

[@SaniaRostovskiy]

Hello. I connected everything as in your video, it worked for about 10 minutes and after that the microphone stopped responding to sounds, everything else works. What could be the reason ? Maybe you can use other contacts to connect? Thank you in advance.

[@3ATIVE]

Have you tried a different microphone?

[@SaniaRostovskiy]

@@3ATIVE No. I don't have another microphone.

[@3ATIVE]

@@SaniaRostovskiy Ah well. Then you'll either have to get another or test the microphone on another setup.

[@SaniaRostovskiy]

@@3ATIVE OK, thank you

[@3ATIVE]

Sorry I can't help much more. I hope you see it's not something I can advise on without seeing your setup.

[@eddiedyer845]

When you use custom text, how do you get a preset back that only has the date and time? No matter what i do, i can have the scrolling text, but i cant revert back to the date/time. Thank you

[@3ATIVE]

There's a couple of ways: Make a Text line longer than 32 characters, or sent it a non-standard character.

[@allatsakis5058]

what if we have not the Digital MEMs I2C Microphone and we have GY-MAX4466 or anuther mic

[@3ATIVE]

It should still work. You will have to adjust your setup to match

[@markstacey6082]

Hi there, great video. How do i enter the password for the wifi? which wifi password and how do i set the esp32 to my own network? i have tried via my phone with my own pw for my own network but it wont connect :(

[@3ATIVE]

Hi, Thanks for the feedback. 👍 To connect to your own Wi-Fi, simply go in to the WLED APP on your Phone at IP address: 4.3.2.1, then the settings are via: "Config" > "WiFi Setup". There you will find "Network name" and "Network password", Simply add you details there then hit the "Save & Connect " button. - If entered correctly you should now be able to control WLED from it's new network IP address, for example: 192.168.x.x

[@allatsakis5058]

when you tap in wled-ap in your phon they ask for password?????????????

[@3ATIVE]

If it does ask for a password, the default is: wled1234
