Please quickly edit your post.

Use the IDE Auto format tool.

Then use the IDE Copy for Forum tool on the sketch.

Lastly, paste it where your code is now.

So it looks like code, viz:

void setup() {

}

void loop() {

}

TIA

Hi
is this with 2 LED strips?
thanks

Hi, how do I edit that?

Without studying your code...

You probably need separate detection of brake and blinker.

If you want to use the existing flasher circuit, you'll probably want to detect the brake and use an if-statement to run a different section of code when the brake is activated.

yes. it mentioned for a bike as regular turn signal lights replacement

Is this so wise, to do your own electrical system in a car? If an accident happens because the breaklights are out, it could have devastating consequences for you and others.

10

but I am using only one LED strip and am using it on my car.
Can you please modify it in a way to be used on one strip please?
thanks

11

not if you know what you are doing.
thanks for your concern.

12

if you please study my code you'll see that I have already done that

13

It's easy to say that, but will you repeat those words if something happens?

With that said, I hope it will be ok.

14

It's unclear that has been established. Otherwise, you wouldn't be here.

pls do what we ask - place you code inside of Code-Tags

16

thank you for noting that.

17

already installed on my car. I am not recommending this to any one else . so use at your own risk. thanks

18

sorry I do not understand . I thought the code is already in quote tags.

21

you can.
copy your sketch,
delete code in first post,
press "code tag",
press Ctrl-V,
click "save post".
profit!

why? turn signals are never together, especially on a real car
