    ESP8266 FastLED IoT Webserver

    This is a fork of jasoncoon's esp8266 fastled webserver that was adapted to control the colors of my LED-Projects.

    New: Windows application to sync the LED devices with music. Completely optional but it's awesome. But it's just the first prototype and very experimental. Software and docs still work in progress.

    What happened here?

    All of my recent project were merged into one including most of the features. A new and optional Windows application allows to sync the LEDs to a Windows audio source of your choice.

    Supported Devices

    Generic LED-Strip, just a regular LED-Strip without special hardware

    LED-Matrix, with a flexible LED-Matrix you can display the audio like a Audio Visualizer

    3D-Printed 7-Segment Clock, display the time, syncs with a ntp server of your choice

    3D-Printed Desk Lamp, a lamp that reacts to sound for your desk

    3D-Printed Nanoleafs, a Nanoleaf clone that can be made for cheap

    3D-Printed Animated RGB Logos, a small 3D-Printed logo that lights up with style

    Changelog

    Web App

    Webinterface

    Webinterface

    The web app is stored in SPIFFS (on-board flash memory) and has around 400kb. All stylsheets/js used are also stored in the spiffs, so no internet connection is required to view the webpage correctly.

    Circuit

    circuit without Logic level converter

    Technical

    Patterns are requested by the app from the ESP8266, so as new patterns are added, they're automatically listed in the app.

    The web app is stored in SPIFFS (on-board flash memory).

    The web app is a single page app that uses jQuery and Bootstrap. It has buttons for On/Off, a slider for brightness, a pattern selector, and a color picker (using jQuery MiniColors). Event handlers for the controls are wired up, so you don't have to click a 'Send' button after making changes. The brightness slider and the color picker use a delayed event handler, to prevent from flooding the ESP8266 web server with too many requests too quickly.

    The only drawback to SPIFFS that I've found so far is uploading the files can be extremely slow, requiring several minutes, sometimes regardless of how large the files are. It can be so slow that I've been just developing the web app and debugging locally on my desktop (with a hard-coded IP for the ESP8266), before uploading to SPIFFS and testing on the ESP8266.

    Alexa

    The code has an optional feature to be able to control the lamp via Alexa on any Amazon Echo device. For setup instructions refer to Software_Installation.md document.

    Compression

    The web app files can be gzip compressed before uploading to SPIFFS by running the following command:

    gzip -r data/

    The ESP8266WebServer will automatically serve any .gz file. The file index.htm.gz will get served as index.htm, with the content-encoding header set to gzip, so the browser knows to decompress it. The ESP8266WebServer doesn't seem to like the Glyphicon fonts gzipped, though, so I decompress them with this command:

    gunzip -r data/fonts/

    REST Web services

    The firmware implements basic RESTful web services using the ESP8266WebServer library. Current values are requested with HTTP GETs, and values are set with POSTs using query string parameters. It can run in connected or standalone access point modes.
