Have set up WLED on ESP32 Development board. I see that some of the Effects are sound reactive.
Do I need to add a microphone to have this feature, or is there something built in to the dev board?
My lights came with a controller that has a small 2 wire microphone. If needed, could this microphone be used?
Thanks to all that entertain my inquisitive venture.
Well, I did find that the microphone could be used, what was needed to connect it and get it working. I now have a 200 foot string of lights on a WLED controller (assembled on my desk) with the microphone attached, a 3D printed case for it, a 76" x 47" sheet of 1/8" plywood with 120 square holes evenly spaced for the 120 LED pucks to go in.
This has been a project for my Granddaughter to go under her elevated bed. The electronics have been at my desk running in sound reactive mode for over a month. All is going well, hope to have it completed in the next week.
I think she will like it.
Well, turns out I did not have the sheet of 1/4" I thought I had. Went and got a 4’ x 8’ sheet of 1/8" plywood (the LED pucks fit better) and 1" x 2" board to stiffen the sheet and give clearance under the bed. Treated the wood after cutting holes and assembling the wood frame for rigidity. Mounted the LEDs and it worked. Until today (I secured the perf board and microphone into the case, tested and the microphone stopped functioning). Tested the mic and it seems ok, Wires ohm out at 0.5 ohm and mic is ~1k ohm. Thinking it is something in the configuratio that shifted.
… and connecting with PC, it works now…
When connected back to the mounted board, the audio function worked (tested prior to mounting perf board into case) and continued to function as the perf board and microphone were placed in case and secured. Then turning the system off, disconnecting from power supply, moving the board, reconnecting to power supply and poering on, the audio function failed. Disconnecting power (without turning the system off) and reconnecting, the audio detection restarted and functioned.
Can anyone shed light on this? Possibly suggest what could be happening/how to reconcile the issue?
Thank you to all that read this and to those that may have insight.
