# Examples:

# internet-detector-led.sh on 2 # turn on LED 2
# internet-detector-led.sh off 2 # turn off LED 2
# internet-detector-led.sh on "nbg6817:white:internet" # turn on LED by sysfs-name (/sys/class/leds/nbg6817:white:internet)

# internet-detector-led.sh on # same as "internet-detector-led.sh on 1" (default <LED number> is 1)
