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 ...

One of the coolest things about old hi-fi hardware is that it often came with flickety needles that danced with the audio level. You can still buy these if you want, or you can simulate the same look ...

The circuit was designed by two monolithic integrated circuits to measure the level of audio signals whose unit of measurement is known as volume unit. Volume Unit – an entity equal to a decibel for ...
