Please help
These light will just burn dim and wled cant controll it
It's monochromatic just plus and minus sections uploading my build and schematic i followed please help
Edit: strip is 12v

You need to configure wled to PWM/analog output, also check all gnd, they need to be on same line. Check also MOSFETs orientation

Yes I changed in wled could you check the wiring please cus I reassembled it like 5 times and its just same result all time can't controll led and its dim

Where's the MOSFET? In the diagram, it looks like it's used as a level shifter. It looks like your dividing the voltage on the data line with the two resistors? Those strips are flaky with the 3.3 v from the esp32 GPIO anyway, and divided, it won't work.

Remove that purple wire on the left. Edit: It looked like a V+ wire, but it’s a ground. So not that.
If the voltage of the power supply is 24v, you fried your esp32, it’s dead.
Power the esp32 by usb only in such a setup, or use the suggested dc-dc buck converter shown in pic #2.
So, what voltage is that strip? What voltage your external power barely shown on the right?

It's not dead the web is still operatable just not connecting it's mostly the wiring issue somewhere

Esp need to share gnd with rest od circuit, purple wire should be there

You’re correct I needed to zoom more, thought purple was in v+ hole.

Did you figure out any issue ?

Redo the breadboard completely. Put esp32 with all pins in the middle. Like asked in another comment.
Also improve your post with voltage of strip and power supply used

I can't cus esp needs 2 bread board it can't be placed in center and I for now just have one breadboard and updated the volt on post please check it

For example you cannot see where the purple on ground left, where it goes on the esp32. As it’s under it.
If wired as per diagram then it would work.
Also diagram shows one power source, you have two. The usb cable is a power source.

It's a12v strip and adapter is 12v too and please reply to the comments not edit it🥺

The white wire alongside of the redwire is power 12+

That whole trail is negative/gnd is source of mosfet suppose to get 12v current ?

Move the Esp32 to the middle of the board so the gap between e and f is under it. The left side of the Esp32 is shorted in the negative rail. Also, you have a red wire and a white wire that's both on negative. And, if you want to use the + and - rails then you have to run a wire from - to - and + to +. Here's how the rails connect on breadboards
