Hello! Please tell me whether it is possible to make a design similar to the devices on Govee Curtain Lights - Customize Your Own DIY Light Show on a WLED device assembled on ESP8266, or ESP32, or <a href="https://www.aliexpress.com/item/1005005300319300.html?spm=a2g0o.detail.0.0.1858aepZaepZ2d&gps-id=pcDetailTopMoreOtherSeller&scm=1007.40000.327270.0&scm_id=1007.40000.327270.0&scm-url=1007.40000.327270.0&pvid=8a9f286c-daf8-4f4d-b0c4-f9a38a19e1b0&_t=gps-id:pcDetailTopMoreOtherSeller,scm-url:1007.40000.327270.0,pvid:8a9f286c-daf8-4f4d-b0c4-f9a38a19e1b0,tpp_buckets:668%232846%238111%231996&pdp_npi=4%40dis%21GBP%21112.98%2133.25%21%21%21972.33%21%21%4021165f1216982977279314399ef694%2112000032546636443%21rec%21UK%21%21AB">https://www.aliexpress.com/item/1005005300319300.html?spm=a2g0o.detail.0.0.1858aepZaepZ2d&gps-id=pcDet…

Yes you can use this with WLED. You would use 1 data pin. If you want the WLED fx to look correct I think you would have to create a custom LED Map for the matrix. Mapping - WLED Project I use one of these curtains connected to WLED in 1D with xlights controlling it. I have attached a pic of my …

divsys , thank you very much for your answer. I will study. This is completely new information for me.

Profile - Jinx - WLED , thanks for the answer. So far I have no idea what “xlights” are). I’ll try to figure this out.

Profile - Jinx - WLED , did I understand correctly that your example uses a 4-wire tape with data return? And in this case, at the bottom of each piece of tape, the data transmission wire and the data return wire are connected together, and then from the 20 LED goes up (purple wire in the figure) and…

My approach that divsys linked to has exactly that. An embedded 4th wire that takes the signal back up and to the next strand. All of the prebuilt curtains I’ve seen have used 10cm pitch (4” spacing). You can build your own with 4x as many lights for less.

Thanks for the answer. How does the fourth wire work? I can’t find the electrical diagram. Does it seem to go right through? Those. you can test it with an ohmmeter, and it will show 0 ohm, i.e. Is there a short circuit in the area from the first LED to the last? Can you tell me where I can see this…

There’s a picture in the previous link: [image] And yes, the return line is effectively just one more wire bonded to the normal set of 3. You can use it for anything you want, but it works well as the data return.

[image] Mobiart: Profile - Jinx - WLED , did I understand correctly that your example uses a 4-wire tape with data return? My example xlights model was using a curtain like you linked to. Those curtains do not have a 4th return data wire. They either have a little circuit at the top of each dr…

divsys , thank you very much for your detailed answer. I will study. If possible, please send me a link to the store where the 4-wire tape is sold.

Is it possible to do this at WLED?

Take a look at a current project exploring this issue: Modular Matrix build It’s quite a well thought out approach.
