I have been searching for over a year now on how to get a dual color led to work with my motherboard. Ok, the motherboard has a constant negative and uses the positive pins to turn the power and HDD leds on/off. Now, the dual color led has a common positive and uses 2 negatives to operate both colors. I was thinking of a PNP transistor but at this point any suggestion would be really appreciated.
Thanks for the reply, I made a diagram of my setup, (yeah, I used paint brush lol) and I think I want to try the NPN transistor, now i'm very visual so if you can modify my diagram I would really appreciate it. Thanks
