If you are looking for an updated way to calculate resistor values ( R1cap R sub 1 R2cap R sub 2 ) for the LM3915 Logarithmic Dot/Bar Display Driver Go to product viewer dialog for this item. I can provide a customized schematic layout description

The LM3915 is a legendary chip. For decades, it has been the go-to solution for anyone building audio level meters, battery monitors, or any project requiring a visual representation of a logarithmic signal. While newer microcontrollers offer customizable displays, the LM3915 remains popular for its simplicity—it requires no coding and drives 10 LEDs directly with a beautiful logarithmic decay.
