conception d'un vumètre à leds.

This paper describes a method of designing a LED meter, based on the use of AOP-mounted voltage comparator. It will help you, I hope so, to realize the meter you dream for so long, with the number of LEDs and progression of scale as desired.
Note: You can find several schematics, which are noted several voltages. All voltages are measured with respect to ground, which serves as reference point.
