I’m new to the forum so if this isn’t the correct location to post this I’m sorry.
Anyways, I’m hoping you guys with more electrical experience can give me a hand. Over the last few years I’ve gotten big into cars. I have always like the look of sequential/chaser turn signals so I wanted to create some for my car. After doing some research it seemed like using an arduino and some WS2812B strips would be my best option since I have some programming experience and not a whole lot of electrical experience. Anyways, I ordered an arduino uno and a strip of LEDs and begin to practice programming for them using the FastLED library and was able to create a pattern that I liked.
Now I’ve run into my first real roadblock. Since the car’s electrical system uses 12v and both the arduino and LED stip use 5v I’m not to sure what the best course of action is. My plan is to solder wires to the existing plug on the housing and use that as a signal wire to the arduino. While also using some form of constant power to wire the arduino and LEDs. I’m just not sure how to go from 12v to 5v for both the signal power and the constant power. So if anyone has any suggestions that would be great.
TLDR: Need to go from 12v to 5v to power arduino and a WS2812B of LEDs.
