Wled for cars is it possible and what hardware should i use?

@djfuego Hello. I intend to venture into in-vehicle “club experience” lighting myself. If time/resources permit, I will begin prototyping in December. This is what I have in mind (assuming 12v powerlines):

  • A 12v-to-5v DC step-down buck converter for the ESP32s (or ESP8266s). Just DuckDuckGo or Google “12v to 5v dc buck converter for vehicles” for links on Amazon, ebay, walmart, etc… or just inquire from your local mechanic!

  • 12v WS2815 LED strip; No need for high-current DC buck converters as required by 5v strips such as WS2812. Nevertheless, do some WLED/WS28125 background research e.g:

For “light up on approach”, “cool color sequences on ignition”, etc, you could borrow ideas from a project such as this one. Essentially, it implements a usermod which does a bunch of interesting things, e.g. sequentially light up the steps on approach, switch off the steps after you, etc

Hope this helps!
