Audio reactive lights using Teensy 3.2 with 4 audio reactive modes and 2 strobe effects

• Teensyduino
• Adafruit's NeoPixel library

• Addressable LED Strip (WS2812 or WS2812B) (like this one)
• Teensy 3.2
• 1x Push Button
• 1x 2.2K Resistor
• 2x 10K Resistor (one of these is for the pushbutton)
• 2x 47K Resistor
• 2x 10µF Electrolytic Capacitor
• Wire
• Veroboard (larger piece for the audio circuit, smaller piece for the pushbutton)
• 5V (>2)A power supply (your computer will not be sufficient to power the LEDs at full power)
• Optional: Translucent plastic tube (this was for my own design, however paper works well enough)

1. Flash the Teensy with the code in this repo
2. Build the audio filter circuit as found in the Teensy Audio System Design Tool on the veroboard
3. Build a simple pushbutton circuit (example here)
4. Plug everything together (pushbutton to pin 2, LED strip to pin 6) and you should be set!

(If you need more detailed instructions or I've missed out something crucial, please flag an issue and I'll get on it asap)

These are some example videos of what the tube looks like when built
