Limit the frequency of LED status updates

Browse Source 
Unrestricted refreshing of the LED status may cause the WS2812
controller to not work properly.
Observed on my waveshare_rp2040_one board where the LED remains
either constantly on or off, even though the workflow should
dim or turn off/on the LED.
