For 35 LEDs at 55mA max current, you are getting close to 2A at full power. That could be a bit high for those small traces on the ESP32 and potentially fry the board. You might want to consider using an external power source instead of feeding power through that Vin pin (which is directly connected to the USB power). While it can work for small current applications, Vin should really be used only for input power to the board, not out.

Great tips, thanks for sharing!

OMG Thank you so much! This is exactly the tutorial I was looking for and your timing is absolutely perfect! I have just finished building a stage decor for my DJ boyfriend with 2 ESP32s, WLED soundreactive, 1048 adressable RGB LEDs and 4 hologram fans, it looks like a cyberpunk city skyline. We've succesfully installed it in the club last week and will be using it in public for the first time tomorrow but I already feel frustrated with WLED's interface. I figured it would be the perfect time for me to learn how to use TouchDesigner but had no idea how to interface it with the leds I have a spare ESP32 at home and leftover LED strip that I can practice with I also laid my hands on a pair of Azure Kinect DK... I have so many ideas and so much to learn now 😅

Thanks so much for posting this video, it is very helpful. I am having issues with my WLED. I have the ESP32 connected to my MacBookPro WLED-AP wifi and the WLED app opens on my computer. I have it routed to the correct pin but it is not controlling the lights correctly. The lights turn on and flash but they are not responsive to the program. Any ideas? Thank you!

[@deargcass]

Finally got the WLED to work. The GPIO wouldn't work out of d2 but would work out of GPIO 16 and pin 16.

[@TheInteractiveImmersiveHQ]

Glad to hear you figured it out!

[@ChrisRodriguez9694]

how many LED strips can you control with one ESP32 board?

[@TheInteractiveImmersiveHQ]

It really depends on the effects you're building and the FPS you're looking to achieve. This site (quinled.info/2021/03/23/max-amount-of-addressable-leds/) mentions that the max amount of LEDs controllable with an ESP32 is 1000 LEDs @~70fps, 2000 LEDs @~35fps, 4000 LEDs @~18fps.

@@TheInteractiveImmersiveHQ thanks!

[@ianncaianni1553]

if i have like 300 leds, how can i control it all? seems like it limited to ≈200 because of dmx can handle only 512 samples on 1 channel. any suggestions? thanx for the video! my setup works well, except this limit

[@GRiMETiME]

did you figure this out

[@michaelfjsmith2]

Has anyone run into the issue of no wifi page coming up after you press next after install

[@jlui1200]

I don't remember exactly, but I believe I've encountered this. I think I solved it by clicking the 'Install' button again, then the Wi-Fi set up window showed up again, if I remember.

[@omargomezgonzalez8919]

EVERYTHING WORKS PERFECTLY WHILE THE ESP32 IS CONNECTED DIRECTLY TO THE COMPUTER, BUT WHEN CONNECTING IT TO AN EXTERNAL SOURCE IT NO LONGER CONNECTS TO THE NETWORK BY ITSELF, AND IT IS NECESSARY TO CONNECT IT AGAIN TO THE COMPUTER TO CONFIGURE IT AGAIN, AFTER THAT I CAN DISCONNECT IT BUT IT LOSES CONNECTION AFTER A WHILE, PLEASE HELP

[@justmaybe5643]

What's your power source? Are you sure it's getting enough power to fully boot? ESPs will often light up and appear functional with minimal power, but won't actually boot without proper power

[@TheInteractiveImmersiveHQ]

Agree w/ @justmaybe5643's response, I would double check that you've got enough power to fully boot.
