I have this low battery detector I’m trying to output to a Nano.
The op amp outputs to HIGH when the battery voltage is less than 12.3v.
I’m hoping to output the op amp signal to a Nano, but I thought the voltage should be reduced before reaching the input pin.
Until I know it all works, I’d like to keep using the op amp output to turn on the LED, while also outputting to the Nano.
Can you offer any ideas?
