I have a board that has two LED's on separate circuits, ran by the same 'intelligent' driver (it might not be intelligent). The LED's have resistors before them but I can not see what resistance they occupy.
The traces from the LED's appear to be going into a micro controller of sorts breaking the connection turning off the LED.
One Yellow LED, that reads after the LED (only place i can access) .25v (250mv).
One Red LED that reads after the LED 1.65v.
The Red one stays ON all the time, and ideally I only need it ON when the yellow one is ON, more for aesthetics.
I was thinking about using a transistor of some sorts to act as a switch, turning off the Red LED when the Yellow LED goes out.
So my understanding is that I need the gate to be around 250mv and ideally as low of a current draw as possible so it doesn't upset anything.
Is this even possible?
Regards
