Battery Voltage Monitor with LM3914
Hi designers!
This is a simple circuit for monitoring the voltage of a battery, requires few components and easy to purchase. You can use linear mode or voltage level per led. The adjustment of this assembly is quite easy: from the 50k potentiometer the maximum limit of the measuring battery voltage is adjusted and from the 5k one the minimum voltage limit is adjusted. For a visual look, I recommend using a colored bargraph led. P.S. I'm not the author of this montage, I just drew it.
