Solution submitted to the AT&T Connectability Challenge: http://connectability.challengepost.com/. Our solution requires some additional hardware & software components.
Hardware:
- Arduino UNO (or other compatible microcontroller)
- MSGEQ7 Spectrum Audio Shield: https://www.sparkfun.com/products/13116
- Neopixel (WS2811 or WS2812B) Individually Addressable LED Strip: http://www.adafruit.com/products/1376
Software:
- Adafruit Neopixel library: https://github.com/adafruit/Adafruit_NeoPixel
- Arduino IDE: https://www.arduino.cc/en/Main/Software
- CymaSpace Cymatic Lighting Software Sketch: https://github.com/CymaSpace/Cymatic-Lighting
Step 1: Connect Sparkfun Spectrum Audio Shield to the Arduino (it will fit exactly onto an Arduino Uno).
Step 2: To quickly get up and running follow the steps in the Adafruit Neopixel Uberguide: https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library
Connect the +5V input on the LED strip to the + (positive) terminal on the Arduino/Spectrum Shield, DIN to digital pin 5 on the Arduino/Spectrum Shield, and – (minus or GND) on the strip must connect to a GND pin on the Arduino/Spectrum Shield (there are usually several — any will do).
Step 3: Install Arduino IDE & Arduino NeoPixel Library (again reference Adafruit Neopixel Uberguide for more detailed instructions).
Step 4: Download our software sketch '/Cymatic-Lighting' from Github and unzip the contents into your Arduino Sketches folder.
Step 5: Upload sketch from Arduino software IDE to the Arduino hardware (make sure USB cable is connected to computer if not already!).
Step 6: Plug in a standard 3.5mm audio cable into either audio jack on the Spectrum Audio Shield and the other end into a sound-source (MP3 Player, Phone, “Handimic” Microphone with line level output etc).
Step 7: Play music or make sound and enjoy the visualization on the LED strip.
