# Setup / Getting Started
Information coming soon. README is currently under active development.
# Setup and Configuration
1. Install Python and Python dependencies
2. [Install Arduino IDE and ESP8266 addon](https://learn.sparkfun.com/tutorials/esp8266-thing-hookup-guide/installing-the-esp8266-arduino-addon)
3. Download and extract all of the files in this repository onto your computer
4. In [ws2812_controller.ino](arduino/ws2812_controller/ws2812_controller.ino):
- Set `const char* ssid` to your router's SSID
- Set `const char* password` to your router's password
- Set `IPAddress gateway` to match your router's gateway
- Set `IPAddress ip` to the IP address that you would like your ESP8266 to use (your choice)
- Set `#define NUM_LEDS` to the number of LEDs in your LED strip
5. In [config.py](python/config.py):
- Set `N_PIXELS` to the number of LEDs in your LED strip (must match `NUM_LEDS` in [ws2812_controller.ino](arduino/ws2812_controller/ws2812_controller.ino))
- Set `UDP_IP` to the IP address of your ESP8266 (must match `ip` in [ws2812_controller.ino](arduino/ws2812_controller/ws2812_controller.ino))
- If needed, set `MIC_RATE` to your microphone sampling rate in Hz
# Running the Visualization
Once everything has been configured, run [visualization.py](python/visualization.py) to start the visualization. The visualization will automatically use your default recording device (microphone) as the audio input.
A PyQtGraph GUI will open to display the output of the visualization on the computer.
If you encounter any issues or have questions about this project, feel free to open a new issue.
