I recently updated my PC motherboard and the new motherboard doesn't pulse the power led when it is sleeping, i liked that on my old board because i knew instantly when i went up to it whether it was off or just asleep.
Im thinking about using a arduino to 'replicate' this, I'm thinking i could connect the arduino to the power LED header on the motherboard and use the arduino to control a LED, (probably the existing LED in the case).
What i would like is when the arduino detects the is power at the motherboard header then the LED is on as normal, but when it detects there is no power there ( i.e. the motherboard has turned the power LED off ) i would like the LED to pulse. ( already had a play with 'fade' in the samples )
But wasn't sure where to start controlling it all.
Thanks for any help.
