Hi all,

I will post my first post on this community to get some help on my project.

I’ll try to build a stairs light system based on WS2801 les strips.

I’d just tested the Fastled library with my setup and I’m able to make some light in my room… I good first step.

Now, I’m searsh how to :

Fading a color from black to full brightness from the bottom to the top ( climb scene) and the same but in the reverse direction ( down scene) . After a delay in both scenario, the led should be go to dark one after one in fading mode .

I’m a real noob in developement, so I’will be very happy to get some help from anyone of you in my project.

Thanks

I just tried to solve theses errors has you’ve said.

I have no more error when I upload the code, but there is no light.

There is no LEDS.show() anywhere in that code.

Ok, I’ start to understand.

Now It work, but I’have taken another exemple :

 CRGB yourcolor = 0xFFFF99;
// First slide the led in one direction
for(int i = 0; i < NUM_LEDS; i++) {
	// Set the i'th led to  
	leds[i] = yourcolor;
	// Show the leds
	FastLED.show();
            delay(60);
}

This is perfect, but how to fading the led ?

Thanks again for your help
