Description:
|
||||
Set the mode of LEDs. You should notice that changing the mode
|
||||
of one LED will update the mode of its two sibling devices as
|
||||
well.
|
||||
|
||||
0 - normal
|
||||
1 - audio
|
||||
2 - breathing
|
||||
|
||||
Normal: LEDs are fully on when enabled
|
||||
Audio: LEDs brightness depends on sound level
|
||||
Breathing: LEDs brightness varies at human breathing rate
