[Sam Kent] and good friends developed a sound-reactive LED display as part of the Leeds (UK) digital celebration and exhibited it at Hyde Park book Club. The installation consists of a grid of 25 tubes, each one constructed out of four recycled 2-liter bottles equipped with a string of a lots WS2812B LEDs managed by a central Arduino.
Connected to the Arduino via USB, a computer running a Processing application analyzes the audio input and tells the Arduino which LEDs to light and when. The red tube in the center responds to bass, the sound of yellow LEDs mids, and the outer sound glows blue in response to high frequencies.
It’s incredible exactly how just a simple 2-liter makes a rather efficient light pipe to amplify the impact of each burst of color. We believe this installation would be a excellent addition to the magnificent LED dance floor we just recently looked at from our good friends up in Toronto. If you seek an LED art piece that’s a great deal easier to move around, what you’re after is a rave buying cart.
