Hi guys,
as in the subject, is there an easy way to check if LEDS are in use?
I'm thinking about adding a relay that would switch off my power supply when LEDS are not used.
This relay would be controlled by RPi GPIO by a python script, that would be checking whether there is any "action" on LEDS for more than 5 seconds. If not then switch off PSU.
Is this even possible?
Right now when there is low power consumption, my PSU generates noticeable noise which sometimes is quite annoying
