I fixed this in #14 by making the flush()
function take more time. I think our new volume dial PCBs might be using a newer version of the WS2812B LEDs. Some info on that here:

- “Old & New chips are exactly the same as in Timing, Data transmission and Data structure. However, the Reset Time increased from >50us to >280us. It won’t cause wrong reset while interruption, and what’s more, it supports the lower frequency and inexpensive MCU. When the “Reset Time<280us”, don’t mixed up and kindly please make necessary amends.”
I think maybe this code is running too frequently and causing stability issues with the LED color:

If I only set the colors when receiving an LED command, it works predictably, but if I just try to update the color without pulsing, it often doesn't change.
