# ESP32 FastLED Web Server
**Work in progress ESP32 port of https://github.com/jasoncoon/esp8266-fastled-webserver**

Control addressable LEDs with an ESP32 via a web browser over Wi-Fi.

## Features
### Currently Working:
* [x] DemoReel100 patterns
* [x] Static web app file serving from SPIFFS
* [x] Ability to adjust these settings via the HTTP REST API:
   * [x] power on/off
   * [x] brightness
   * [x] pattern
   * [x] autoplay on/off
   * [x] autoplay duration
   * [x] speed
   * [x] palette
   * [x] auto palette cycling
   * [x] palette duration
   * [x] solid color
   * [x] twinkle speed/density
   * [x] fire cooling/sparking
* [x] Setting storage in EEPROM

### Currently Lacking:
* [ ] WebSockets for automatically refreshing/syncing web clients
