I am trying to make an LED tachometer similar to the one on this thread:
http://forum.allaboutcircuits.com/showthread.php?t=16291
Mine is on page 13 of the national semiconductor datasheet for the LM3914. I want to use an input voltage from 0-5V, but cannot figure out what resistor values I need to use to do this. Any help is greatly appreciated. Thanks!
here is the datasheet,

the Bar Display with Alarm Flasher is the schematic I'm using.
