variable voltage moinitor

[shahh]

Help,
I am trying to build a variable voltage monitor using color coded 10 leds, that will display the voltage range from high to low. This circuit could be hooked up to any battery voltage source (9, 12, 24, or 48 volts). For eg. if i hook up a 24V battery, it should display ~18V for the lowest and ~26 for the highest.


Thank you
HS

Shah,

The LM3914 is a good choice, take a look at the data sheet: **broken link removed**
Then do a Google search for LM3914 and you can find several circuits that will help you. Good Luck!
