  1. thanks for replying. what resistor values should I use to display a range between 11 and 14.4 volts
  2. hello, I am new in the forum and new with electronics also. I am trying to built this circuit but I wonna display a range between 11 and 14.4 volts. I would be grateful if someone could describe how lm3914 works and furthermore help me calculate the resistor values for this range. I already have download the datasheet http://www.national.com/ds.cgi/LM/LM3914.pdf and a sample circuit http://www.national.com/an/LB/LB-48.pdf but with my limited knowledge on electronics were not that helpful.
