In Fast.Led lib for arduino there is a code to turn off all leds

FastLED.clear ();

Is there also a shortcut to turn all LEDs ON, and with a specific color

  • What leds/driver are you using? – Gerben Mar 18 '16 at 20:09
  • Arduino nano, FastLed lib and WS2812B leds – Niles Mar 18 '16 at 20:14
  • I think you could use showColor – Gerben Mar 19 '16 at 15:19

You can use fill_solid.

For example

fill_solid( leds, NUM_LEDS, CRGB(50,0,200));


fill_solid( leds, NUM_LEDS, CRGB::Red);
