    I want to use a LM3914 LED driver to give a visual indication of voltage and display voltages between 3.3v and 5v, as part of a larger circuit. I came up with a schematic of the resistor values that I believe would work, but I’m unsure if I did the calculations properly. I would appreciate any feedback. I based my design the Expanded Scale Meter as explained in the National Semiconductor datasheet for the LM3914

    Am I doing this right?
