A stereo VU meter built with an Arduino Nano and two NeoPixel LED rings.
From mono to stereo in a BEAT, that's WannaDuino style. Just see the video. It's cheap & awesome. Check out my other VU projects & builds.

Hi, that sounds like a cool project!
The problem most likely is that (distant) sounds aren't amplified enough.
You might want to try a mic with more sensitivity or a higher output pre-amp (or an additional amp).
I only tested the mic I had so I cannot advice you about the best out there.
Try some searching online for opinions of others about this.
Hi Rob, thanks. Although I have to admit the project got more elaborate after adding more features which makes it more tricky to setup.
Hi Rob, the spinning and pulsing function was programmed for using one ring, displaying both the left and right input.
I haven't tested it with 2 rings but it will probably not work correctly - as you found out.
You could make it work by connecting the input signal of ring 1 to ring 2 - then both would display the same 'image'.
