VU Meter or Volume Meter is very interesting project for music lovers. It is kind of an Equalizer, which is present in the Music systems where we can see the dancing of LEDs according to the music, if music is loud then equalizer go to its peak and more LEDs will glow, and if music is low then lesser number of LEDs shall glow. Volume Meter (VU) is an indicator or representation of the intensity of sound level over LEDs and can also serve as a volume measurement device.
Although we can also create a simple VU meter circuit without using any microcontroller but to enhance it and work in a more beautiful way, we have designed it as an Arduino shield. Here you can find the complete DIY tutorial and a step by step guide to design the PCB layout for this VU meter.
Check it out here.
