Hey there :) I am new and need help,

Hey there :slight_smile:

I am new and need help, my goal is to program my sketch in reverse, I already have the running light:

void fillWhite(){
for(int i = 0; i < NUM_LEDS; i++){
leds[i] = CRGBW(0, 0, 0, 255);
FastLED.show();
delay(30);
}
delay(0);
}

I hope somebody can help me, I just want the last LED to go out then to the first LED, of course assuming that all LEDs are on before. Thank you!

Hello what do you wanna do exactly ?

You can use a very similar function that sets one pixel at a time to black,
leds[i] = CRGB(0,0,0);
And have the for loop start at NUM_LEDS-1 and subtract 1 each time through the loop.

(Btw, FastLED does not support RGBW yet, only RGB.)

@Yves_BAZIN I want a running light which runs out. As can be seen at Audi
