A Volume Meter is something like an Equalizer, generally found in the Music systems. There we can see the dancing LEDs according to the music beats, if the music is loud, equalizer reaches to its peak and in low music it remains Low.
In this project we have developed this Volume Meter or VU meter circuit, with the help of MIC, OP-AMP and LM3914, which glows the LEDs as per strength of the sound, if sound is low, lesser LEDs will glow, and if sound is High more LEDs will glow.
You can understand more about the working of this volume meter in the below video:
