  • Running two types of LEDs from a single MCU/Sketch? | 2021-01-19
    Also you may want to check out the FastLED.setCorrection( TypicalLEDStrip ); function which color corrects typical RGB strips to have a more even color balance, so that (255,255,255) looks more right. See and for some more ideas.

    Hier bei Amazon wäre ein Beispiel für so einen LED Streifen. Die sind mit dem Arduino und entsprechenden Libraries (z.B. FastLED) sehr leicht zu programmieren. Das Netzteil muss halt nur gut sein und genug Leistung haben. Einen Summer oder ähnliches kann man ja trotzdem noch hinzufügen.

    Yes, interrupts are (very) unfortunately not a thing with FastLED and WS2812's. See:

  • Finally got my piano connected to an LED Strip! | 2021-01-05
    No problem, it's all controlled using an Arduino and the code was mostly written myself. I use the FastLED library ( to control the lights, as they require a signal with very specific timing. | 2021-01-05
  • Can anyone explain the highlighted lines. I'm new to this and I don't really understand what's going on there. | 2021-01-05 | 2021-01-05
  • setBrightness and setCorrection on multiple strips, different pins | 2021-01-05
    I've never tried this, but I imagine it would follow the pattern of other multi-controller things:
  • Are multiple WS2812 outputs supported? Is the chipset reference up to date? | 2021-01-05
    So I'm not really a software developer or regular github user - excuse my ignorance - as I understand, this feature was developed as branch to the main FastLED library, and then later ported back to it? So I can just clone as usual and then use "#define FASTLED_ESP32_I2S" to tell FastLED to use the pins as parallel interface, correct?
  • New to FastLED and not a seasoned arduino programmer, lcd.printin skipping issue and IR remote issue. | 2021-01-05

    Check out the FastLED -> DemoReel100 example. It's in your Arduino IDE or here. It demonstrates a simple way to show different effects in sequence.
