This project is used to control a WS2812B RGB LED strip using a webpage local-hosted on Wi-Fi by an ESP8266.

The motivation behind this project was so that there would be no need for yet another remote to control the lights as is normally the case. Also, having a webpage allows for easy updates to the software to update and add new functions for the same hardware.

The design has the following components:

• ESP8266 (12-E)
• SSD1306 128x64 OLED Display (SPI config)
• MAX4466 Electret Microphone Amplifier with Adjustable Gain Module
• 10kΩ Potentiometer
• 10μF 50V Capacitor

The current program has the following functions:

• Solid color display
• Breathing color display
• Basic Audio-Visualizer color display
• Color Spectrum

The audio visualizer is based on an FFT transform of the input data from the MAX4466.

I have included the Arduino program, along with the KiCAD project for the PCB design.

• Proper commenting lol
• Select particular audio freq for AV
• Select Wi-Fi network
• Load last config from memory
• Over-voltage protection for components
• Convert THT into SMD (improbable tbh)
