I'm trying to build a 10 segment LED bar graph using a LM3914 voltmeter for a single cell 18650... 2.8v/3v - 4.2v Every place I go for information on what value resistors to use for the voltage divider all have different info.... One place said the voltage has to be 1.25v below VCC. If that's the case that is straight forward.. But I'm trying to clarify....
Im in the middle of Designing the pcb and do have the components yet in order to test my self. And I would like to put the resistor value on the pcb silkscreen layer.
Thank you
