Hi all, I am trying to design a circuit that will indicate battery charge levels for a 12V battery. I have seen many designs online, but they all use diodes to determine the voltage thresholds or work like a meter. I need it to be somewhat precise and turn off/on leds.
I need to indicate when the voltage is between 11.9 and 12.3, and when it's below 11.8, with only one led on at a time.
I know there are people on this forum that are good with op amps/ comparators that can help me put a circuit together that meets these requirements. Please help me.
