Hi all,
I have a challenge for you, a problem for me. I have a circuit that uses a LED membrane, the LED's cathodes are all connected together and to ground on one pin. The anodes are all open for input. Each LED serves as a particular indicator. One of the LEDs was intended to be used as a reverse polarity indicator.
The challenge is how can I activate that one LED when there is reverse polarity?
I have been trying different ways with a bridge rectifier, mosfets, and transistors but to no avail.
Basically, I need it to light up with a voltage on the cathode or make it so that the cathode is somehow diverted to ground during a reverse polarity connection.
Please help me with your ideas! Thanks!
