5m VU meter: Noise-o-Meter in the center "ball" of school
thingiverse
I've made an Noise-o-Meter for fun in our school. It has no function, only show how crowdy it is in the central hall of Summa ICT. The VU meter in't placed yet, but a picture shows whre the place would be. Feel free to make one of this uge "Noise-o-Meter" for yourself. I used cheap Chinese parts, but it works fine. When you use the code and have an other Neopixel strip than 2811 (like 2812b) you have to change the code (max LEDx3 and maybe the HUE colors)
