Welcome to my project WLED!

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

Uses ESP Arduino core version 2.3.0 (latest as of December 2017).

Features: (V0.4)

  • RGB, HSB, and brightness sliders
  • Settings page - configuration over network
  • Access Point and station mode - automatic failsafe AP
  • WS2812FX library integrated for over 50 special effects!
  • Secondary color support lets you use even more effect combinations
  • Support for RGBW strips
  • 25 user presets! Save your favorite colors and effects and apply them easily!
  • Nightlight function (gradually dims down)
  • Notifier function (multiple ESPs sync color via UDP broadcast)
  • Support for power pushbutton
  • Custom Theater Chase
  • Full OTA software update capability
  • Password protected OTA page for added security (OTA lock)
  • Alexa smart home device server
  • NTP and experimental analog clock function
  • Realtime UDP Packet Control (WARLS) possible
  • client HTML controlled
  • Edit page. Change html and other files via OTA. (needs to be enabled in source)

Compile settings:

  • Board: WeMos D1 mini (untested with other HW, should work though)
  • CPU frequency: 80 MHz
  • Flash size : 4MB (3MB SPIFFS)
  • Upload speed: 921600

Quick start guide:

  • If you do not plan to change the software, you can use the supplied binary files instead- Just flash a basic HTTP OTA updater sketch and upload the bin!

  1. Connect a WS2812B RGB led strip to GPIO2. Optionally connect a NO-pushbutton to GPIO0 (internal pull-up) and ground.

  2. Follow a guide to setup your Arduino client (I am using version 1.8.1) with the ESP8266 libraries. For current compiles I use version 2.3.0.

  3. In file "wled00.ino", you should change the access point and OTA update passphrases for added security (you can change them later, this is just the "factory default"). Flash the sketch. You will need to install the NeoPixelBus library by Makuna. All other dependencies are included with WLED for convenience.

  4. Connect to automatically started WiFi access point "WLED-AP" using default passwort "wled1234". Go to the IP "192.168.4.1".

  5. Click on the cog icon to edit settings like connecting the module to your home WiFi.

  6. Have fun with the software!
