LED Volt Meter but for Low voltages

[alarmguy1]

Hi,
I am new to the forums and a bit of an electronics newbie.
I'm looking for a circuit that contains several LEDs
one LED to light when the unit is on and no voltage detected.
one LED to light when 0.2v is applied
one LED to light when 0.4v is applied
one LED to light when 0.5v is applied
one LED to light when 0.6v is applied
one LED to light when 0.7v is applied
one LED to light when 0.8v is applied
one LED to light when 0.9v is applied
one LED to light when 1.0v is applied
one LED to light when 1.2v is applied
one LED to light when 1.4v is applied

I know the voltages are tight, i'm not worried if say the voltage is 0.8v and all the previous LEDs illuminate or if only the 0.8v LED illuminates.

Many thanks for looking

Keith

Do you really intend the steps to be non equally spaced? If so, read my post to this thead.

thanks for the prompt reply
The steps can be equally spaced just my typing skills.

I would be powering the device with a 9v battery and will detect the voltages coming down various cables.

would this be easy to do?

cheers

Then just use an LM3914 (See Eric's calculator)

Many thanks once again, i will give it a try..
