+4. Connect the RX1 pin of your ESP8266 module to the data input pin of the ws2812b LED strip. Ensure that your LED strip is properly connected to a 5V power supply and that the ESP8266 and LED strip share a common electrical ground connection.
+5. 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. Upload the [ws2812_controller.ino](arduino/ws2812_controller/ws2812_controller.ino) firmware to the ESP8266. Ensure that you have selected the correct ESP8266 board from the boards menu. In the dropdown menu, set `CPU Frequency` to 160 MHz for optimal performance.

   - 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. Most of the time you will not need to change this.
