I am about to add led strips to my car. I will have at least 4 zones to start out and might add more.
1. Under carriage
2. Front end
3. External
4. Internal
Doing it now, I will have 4 controllers with either 1 app, or 4 different remotes. Either way, I will have problems trying to get them to sync the way I envision. Raspberry has so much power, that I think I should be able to preset every option I want and enable with my phone. Some simple examples, all zones cool white, or zone 1 flashing green, zone 2 flashing purple, other 2 zones off, or just zone 4 blue. Possible?

  • Yes, no problem. It is a piece of cake for Rpi. I always think that anything stupid human can do, Rpi can do better - remember Google chess playing AlphaGo and Google driverless car?. – tlfong01 May 14 at 2:04
  • Yes, it is possible. But is it the real question? What does it is? How to program it? That would be to broad. – Ingo May 14 at 21:07
  • @tlfong01 so where do I start? I can find a lot of reading for house lights, but nothing for a car. What software do I use? I’m also clueless on writing my own code. – Daasu May 14 at 21:15

Question

Add led strips to my car, ...

One app or 4 different remotes, ...

All zones cool white, zone 1 flashing green, ..., or just zone 4 blue. Possible?

Answer

Yes, with Rpi, no mission is impossible. Your specific user requirement boils down to two generic answers:

  1. Mobile phone controlling a couple of remotes

  2. Rpi controlling a couple of LED strip

You might like to watch the following Open Garage YouTube to get a rough idea of how it can be DIYed using Arduino ESP8266 to do the job. Of course you can also RpiZero WiFi, but ESP8266 WiFi is cheaper and smaller.

Yes, I know you are not opening a garage door, but the circuit of ESP8266/RpiZW controlling a remote which in turn switches on.off a garage door motor or LED strip is almost the same.

For LED strip, you can read the Lady Ada tutorial and a question on LED strip to get a rough idea of how to use Rpi to control the WS2812 LED strip. This part is a little bit difficult, unless you use AdaFruit libraries.
