Hi all,
Before I begin, to mitigate replies about not altering exterior vehicle lighting, etc... This project is for show only and not intended for road use, no ordinances against it, not breaking any codes, all that jazz...
I have a show car with a set of aftermarket tail lights, and the turn signals consist of 16 LEDs arranged in an arrow in the direction of turn.
With the current arrangement they all blink simultaneously like a normal signal.
What I'm trying to do is to get them to stack/chase with each blink, i.e. LEDs go 1 - 1,2 - 1,2,3 - 1,2,3,4 - 1,2,3,4,5 [...] 1,...,16 then after a pause, repeat.
I found some ways to get them to sequence with a 555 timer and two 4017 ICs but I'm not sure how or whether they'd stack as well. Unfortunately my digital-electronics knowledge has all but faded away since school. I've seen a you-tube video with the same lights made to be sequential but the author hasn't responded to my inquiries about the setup.
Any help would be much appreciated.
Thanks.
