I built this a short while ago as an idea to use in a primary classroom setting. Poster displays are often used by primary teachers wanting to control the noise levels in their classrooms but I wanted to add technology to make it dynamic and responsive. The motivation for this came after seeing the Adafruit Digital NeoPixel LED Strip online and realising its potential as part of a VU meter. Everything else developed from this.

Adafruit NeoPixel Digital RGB LED Strip – White 60 LED – WHITE: You thought it couldn’t get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, its 1.875 times as many but that’s within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticeable strip color – this strip has white-colored flex PCB, which will be less visible against white-painted walls. This is the strip with white flex PCB, its identical to the black 60 LED/meter except it has a different color mask on the flex strip. (read more)
