LM3914 12V Battery Monitor

Postby sammy123 » Thu Feb 12, 2015 9:13 pm

I am trying to make a Battery Monitor Circuit using a LM3914 to drive 10 LEDs. I have found this circuit design but don't know how to calculate the values of the resistors..as in what formulas to use etc. I want one LED to be on at 11.5V and all 10 to be on at 12.8V.
