Reply To: Fastled ws2812b synch with audio DFplayer mini

Hi Hans.

Help improve on this code so that the led animation runs smoothly, maybe with use of millis.

Below is the video of how its running. notice the red and green lighting have to move first before the other blue circles the ring. I want them to move seamlessly.

Thanks
