Hello , I have buy an led garland on Aliexpress (this model : https://www.aliexpress.com/item/1005005955549454.html, which was sold as an WS2811 led light on 12v DC. The led can be controlled with an IR remote to produce effects.
So I installed Wled onto a wt32-eth01 v1.4 card, all is ok for this part.
I have disassembled the controller and there is a thing that I don’t understand :
I have a + and - wire on input, and the same on the output and , the data wire was soldered with the + 12v wire.
With my wled controller, I put the 2 grounds in common (12v and 5v for esp),
put 12v dc on the + & - wire,
and used the gpio2 for data pin, and tried others, but without success.
With the 12v , the string light on fixed white colore, but nothing change when I want to use some wled effects.
I can’t identify what kind of ic is used with the pcb, because the marks on the ic chip seems be erased.
Seems that might be done so that one set of LEDs lights with one polarity and another set does when swapped, and the controller just swaps polarity sometimes.
I think if you remove those white plastic cover balls it will look like these… these are 2812b based RGB/GRB fairy lights, I’m making a big lighting project 20(parallel)x100 with these fairy lights using this super WLED
Oh, what a pity!, I had chosen this led strip thinking it was ws281xx addressable leds.
Here are some new pics of the leds without the cap.
Sorry for quality, but the phone is on Macro-mode , and the chips are really small.
So, I will rewire the original controller, and give them to my parents.
They don’t have an Home Assistant automated house like me, and a manual remote for the effects will do the job for they…
Thank you at all the reacting people,
I will now search a new really addressable string (but with g40 bulbs this time! )
I bought a similar looking rgb fairy light strip. I took the DO marked wire from the pcb and connected it with my ESP32 running WLED. For powering I kept the v+ and gnd on the original pcb.
I am able to turn the lights on and off with WLED but the colors of the leds keep changing all the time even if I only use the “solid” effect. I have tried all different types of LEDs available in the configuration.
The sheet which came with the strip says “output: spi rgb” but as far as I can tell, spi would require a fourth wire for “clk”?
I have read, that maybe the voltage on the data wire is too low, coming as 3.3v from my ESP. Could that be the reason for addressing the leds in a wrong manner?
How do you connect and control your led strips?
