Create sketch that maps A4 style animation to a 54 LED equilateral triangle.

Incorporate reverse order mapping of same A4 style animation for a separate triangle instance on a separate digital pin out.

Incorporate #1 into same sketch from a 3rd digital pin out.

Eartrumpet Labs have provided a high end condenser microphone to serve as the primary interaction point for the triangle installation. We have installed ws2812b addressable LEDs on the inner circumference of the diagraphm ring and need a simple sketch that will subtly glow to entice participants to the microphone. The glow animation will burst into spinning sound-reactive light and color when the participant makes a sound.

Prerequisites:

• Teensy 3.1 with Audio Library OR Audiolux One / Arduino with MSGEQ7 shield
• FastLED Library
• WS28xx LED strip
• LED count: 27

Suggestions for visualization:

Map color to frequency
Map speed of spinning animation to amplitude.
Animation must be a continuous circle (meaning LEDs loop back on themselves).
Implement easing so that animation speed smoothly ramps up and down with a sense of inertia.
