I'm a beginner in arduino, I've studied some programming for my study but this was not really for electronic use, it was more for industrial program or ladder one.
I've done some project on arduino like using a switch level to my reverse osmosis, and some other thing kinda just fun as lcd touch display.
Now I have a new project for a friend's car, it's would be to put a lot oh led in the rear light (brake, tail light, reverse). I've seen some on some new car and found that it was pretty sick, here you can see an example of what, I'd like to do, perfectly but for the beginning, it should be only a brake dimming light (2 level) and a little moving if it could be implemented: https://youtu.be/YMZUKWtS4kQ
In the perfect case that would look like this. If done some search but as I'm not fixed in the number of led, the size, but I was thinking for about 1-200 minimum of 5mm red led ?
My search wasn't really concluded because I only found matrix pr pwm high power led which isn't my case :/ So to recapitulate I need to manage a lot of led, one by one and with different intensity, maybe 2-3 level will be enough.
Finally, to make the traveling effect, is there any functions to do this expect writing line by line every led to be one or off ?
Sorry for my nooby question as I'm not really formed for electronic application.
Thanks in advance
