I made a battery indicator with lm324, and the video shows you the detailed production process. The circuit is simple and the components are few. I hope this video will be helpful for you, thanks for watching.
The circuit divides the battery voltage into four levels and compares it with the same reference voltage (provided by a 5v Zener diode). As a comparator, lm324 outputs the corresponding high and low levels by comparing the voltage values of the two input terminals.
