Hi All,
This is my first post to the forum, and I was wondering if any of you could help me.
I am making a small device that will sit in the front of my computer case. I currently have a red LED to show that hard drive is thinking, but I would to show green when it is not.
I have been looking at multi-color LED's, and there are 3 legs on the LED. I suspect one for ground, one for red, and one for green.
The motherboard on my computer only has 2 wires, one for power and one for ground. I need to make something that will detect if there is power going into the LED, so that if there isn't, I can enable the green leg, and otherwise the red leg.
If anyone could help me out on this, it would be greatly appreciated.
Thanks in advance,
P.S: If you need any more info on what i'm doing, please reply or email me at tim_l_012@hotmail.com.
Thanks again!
