Hi. I have LED strip lights on my truck already, one on each side with yellow & white. Yellow is for turn signals, white is courtesy. The turn lights flash all at once. I'd like to see them as sequence or sequential flashing. I read on a prior post here about a motorcycle doing similar. The lengths of my strips are 80". If Arduino can be setup they would be original. I need to know what I need to get in order to make them if it can be achieved. Thanx.
You need a strip of addressable LEDs, either Neopixel or DotStar. Google them along with the word AdaFruit for more information.
Just a note, the processor used in the Arduino has a restriction put on it by the manufacturers that it should not be used in automotive applications.
You can buy automotive versions for many AVRs including the 328P on the Uno. Check with Microchip/Atmel.
The biggest difference is the working temperature range but there may be other hardening against EMF.
