# Overview
The repository includes everything needed to build an LED strip music visualizer (excluding hardware):

- Python Real-time visualization, which includes code for:
  - Recording audio with a microphone ([microphone.py](python/microphone.py))
  - Digital signal processing ([dsp.py](python/dsp.py))
  - Constructing 1D visualizations ([visualization.py](python/visualization.py))
  - Sending pixel information to the ESP8266 over WiFi ([led.py](python/led.py))
- Arduino firmware for the ESP8266 ([ws2812_controller.ino](arduino/ws2812_controller/ws2812_controller.ino))
