 WLED is a basic, fast and (relatively) (ok, VERY relatively) secure implementation of a ESP8266 webserver to control Neopixel (WS2812B) leds

-Features:
+Uses ESP8266 Arduino libraries from 15th August 2016! Untested with newer version!
+Contents in the /data directory need to be uploaded to SPIFFS.
+
+Features: (V0.2)
 - RGB and brightness sliders
 - Settings page - configuration over network
 - Access Point and station mode - automatic failsafe AP
- Edit page. Change html and other files via OTA. Support for ArduinoOTA.
+- Edit page. Change html and other files via OTA.

+Additions for V0.3 (nearly complete!)
+- WS2812FX library integrated for nearly 50 special effects!
+- Nightlight function (gradually dims down)
+- Notifier function (multiple ESPs sync color via UDP broadcast)
+- Support for power pushbutton
+- Full OTA software update capability
+- Password protected OTA page for added security (OTA lock)
