Circuit Design Help: LED Circuit that can be powered if positive and negative are reversed?
I am looking to design a circuit with:
• Has 10 LEDs
o 5 LEDs in Series, with two of these sets connected in parallel.
• I want the capability of the LED array to illuminate if one end of the PCB is powered by the positive and the other end is in contact with the negative. And vice-versa, meaning the first end is now touching negative with the other end in contact with positive.
o I was told that I can use diodes, but I’m not sure by what configuration.
I've attached something I've found online. Will this work? if so, can you provide an explanation of how it works?
