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.

• DemoReel100 patterns
• Sam's multi-core support
• Static web app file serving from SPIFFS
• Ability to adjust these parameters via the HTTP REST API:
  • power
  • brightness
  • pattern
  • autoplay
  • autoplay duration

• Setting storage in EEPROM
• More patterns
• More parameters
  • speed
  • solid color
  • fire cooling/sparking
  • twinkle speed/density

[Adafruit NeoPixel Ring]

• 3.3V to 5V Logic Level Shifter (required if LEDs "glitch")

Recommended by Adafruit NeoPixel "Best Practices" to help protect LEDs from current onrush:

• 1000µF Capacitor
• 300 to 500 Ohm resistor

• Arduino
• ESP32 Arduino Libraries & Tools
• Arduino ESP32 filesystem uploader

• samguyer/FastLED
• ESP32 Arduino Libraries & Tools
• ESP8266/ESP32 WebServer

To fix an issue with serving files from SPIFFS over the web server, I used Yves BAZIN's fix here: https://github.com/hpwit/lib

Copy libspiffs.a to the ESP32 tools directory: \Documents\Arduino\hardware\espressif\esp32\tools\sdk\lib\libspiffs.a

And copy esp32fs.jar to the Arduino tools directory: \Documents\Arduino\tools\ESP32FS\tool\esp32fs.jar
