For an upcoming liquor brand installation ( shall absolutely remain nameless ) we were tasked with creating a flexible audio – visualizer that would take music or sound and display it in some format on a giant RGB LED bottle that we have fabricated. Originally we considered using an AT-tiny or Arduino uno in conjunction with a small microphone, but after some investigation and thought we decided to abstract out the light control from the audio visualizer. The visualizer it’s self is written in Cinder and allows us to change the visualization or switch between visualizations. The program sends commands though serial to an Arduino which translates the instruction and tunes them into I2C commands that turn the lights on and off. The ultimate installation will contain over 300 LEDS arranged into columns. We also chose RGB LEDs with 4 extra bright LEDs per controller, allowing for a brighter, larger installation.
