I am wanting to change the LED's in some alarms I have.
I have ordered some blue leds with a cathode and anode connections. The board that they need to be connected to has two wire sone red and one black.
I am persuming that the black wire is negative and the red wire is postive.
The question I have is to what does the cathode connection on the led get connected to and vice versa.
many thanks
