McLighting v3 - The ESP8266 based multi-client lighting gadget

McLighting (the multi-client lighting gadget) is a very cheap internet-controllable lighting solution based on the famous ESP8266 microcontroller and WS2811/2812 led strips. It features among other things a web-interface, a REST-API and a websocket connector.

Because of it's open architecture and APIs it's easy to build new clients for different platforms (iOS, Android, Windows Universal Apps, Siri/Cortana integration, ...).

The Hardware

The project is based on the ESP8266 and WD2811/WS2812 LED strips. There are many variations of the ESP chip out there, but for beginners we suggest a NodeMCU dev board, as these are as "plug 'n' play"as it can get. A standalone ESP8266 or an Adafruit Huzzah should work too.

The RGB LED strips are also available in many different flavours (as strips or as standalone LEDs) and can easily be chained.

Used Libraries

This project uses libraries and code by different authors:

• esp8266 tested with version 2.7.4

• WiFiManager by tzapu (tested with version 0.15.0)

• WS2812FX by kitesurfer1404 (tested with version 1.3.1) included in code.

• WebSockets by Links2004 (tested with version 2.3.0)

• Adafruit NeoPixel by adafruit (tested with 1.7.0)

• Optional: PubSubClient by knolleary (tested with 2.8.0) Only when you have activated MQTT in definitions.h.

• Optional: Brzo I2C by pazko-zh (tested with 1.3.3) Only when you have activated GY33 in definitions.h.

• Optional: FastLed by FastLED (tested with 3.3.3) Only when you have activated custom animations in definitions.h.

• Optional: IRremoteESP8266 by crankyoldgit (tested with 2.7.12) Only when you have activated IR-Remote in definitions.h.

The sketch also uses the following built-in library:

• Ticker by @igrr

Parts of the code were taken or inspired by the following sources:

• HSB3RGB conversion

• TV simulator logic inspired by BulldogLowell

• SPIFFS Webserver by Hristo Gochkov

Thank you to all the authors for distributing their software that way. I hope I didn't miss any sources and mentioned every author. In case I forgot someone please let me know and I will fix it.
