WLED - Reactive to sounds?

Hardware
1

Hi all,

I’m just wondering if anybody know what needs to be added to make the WLED lights on a 8266 board react to sounds? I made a cloud light for a friend with addressable leds and thought it would be pretty cool to add the ability for the lightning to react to thunderstorm sounds. I assume some kind of microphone would need to be placed on the board?

Thanks for any information you could provide.

There are a few tutorials out there, and most that I have seen reference the audio reactive LED strip found here:

I tried out ledFX on a laptop to control wled, works great!

Does anybody know if this can be connected to a spare raspberry pi and then transmit real time led sound control?

I can’t find any straightforward documentation on how to do it.

I think LEDfx can do it though I have not tried it yet. You would first have to look up how to get the Pi to recognise that microphone then install LEDfx. It should work like that standard linux install.

There is a fork of WLED with mic and line-in sound reactivity. They have a sub-channel on the WLED discord server, and the wiki is pretty informative including wiring diagrams and mic tests.

You can refer this wiki page created by the author of WLED for the pins of Microphone to get connected with ESP32.

But if you need them for ESP8266 nodemcu refer this Detailed sound reactive WLED article , it has circuit diagrams for connecting with nodemcu.

From what I’ve seen performance wise your better off using an ESP32… Those can be sluggish…
