The project is based on LM3915/LM3916 to produce a VU meter with the level indication using 10-segment LED bar graph. The VU meter circuit was built on a breadboard with a few components used such as ...

The circuit was designed to create a volume unit meter that would be used to measure the intensity of audio or sound level. Volume Unit (VU) – an entity equal to a decibel for expressing the magnitude ...

VU is an abbreviation for volume unit. Thus, a VU meter is a device for measuring the level of sound intensity with audio equipment, such as amplifiers and tape recorders. Although the measurements ...
