Anybody wanting to do anything with LED lighting owes it to themselves to look at WLED. Lots of built in effects, web gui, super cheap ESP32 (or ESP 8266!) as the controller, sound-reactive, etc etc etc. WLED is running my indoor Christmas lights right now and they look great.
- willcooke 3y agoThe actual string I have is three wires. Data and + - it’s likely they have been swapped out for cheaper lesds now, or the picture is wrong.
- willcooke 3y agoI looked at the picture again, it does show a three wire set up.
- MarkusWandel 3y agoThe WS2815 (12V version) actually is a 4 wire setup. It has a "backup data wire" that allows a single failed LED unit to be bypassed. http://www.normandled.com/upload/201808/WS2815%20LED%20Datasheet.pdf http://www.normandled.com/upload/201808/WS2815%20LED%20Datas...
- bloggie 3y agoThere are individually addressable leds that have their ‘address’ burned into them and use a ws2812-style protocol, it could be that. There will only be one continuous data wire, which is cheaper to assemble and resistant to single LED failures.
