Hi,
I know that on the 48 LED illuminators from Hong Kong there is this features (that I’ve disable lol). I think it is controlled by a transistor and there is a light sensor…

you could also do that easily using an Arduino & a light sensor

Good idia,
Now I use MakeController, but I search for more simple decision. I wish to use a useful thing for the decision of such simple problem.
For example:
To connect LEDs to the FAN socket on a system board and operating fan turns to change power of LEDs smile)

Sorry for bad English. In Russia with it hardly.
