HI Slipstick .. ooops
Sorry i have been doing a lot of coding and forgot that it was fade up.
Here's the code
void Scene_01_fade_up ()
{
for ( int i = 0; i < NUM_LEDS; i++ )
{
leds[i] = CRGB::Orange; // Can be any colour
leds[i].maximizeBrightness(FastLED_fade_counter); // 'FastLED_fade_counter' How high we want to fade up to 255 = maximum.
}
FastLED.show();
FastLED_fade_counter ++ ; // Increment
}
