Webbino is a webserver for Arduino. I originally wrote it for my SmartStrip project, which required several unique features which were not present in other webservers that were available at the time:

  • Compatible with many network interfaces:
  • HTML pages and other data can be embedded in the code. This avoids the need of an SD card for simple sites.
  • If you prefer, HTML pages can also be stored on an SD card (long file names are supported!)
  • Tags like $WHATEVER$ in HTML pages can be replaced at page request time, allowing the delivery of dynamic contents.
  • Arbitrary functions can be associated to a page, to perform any needed actions: turn on LEDs, relays, save data to EEPROM, etc.
  • Supports HTTP Basic Authentication.

To learn how to use the library, I strongly recommend to have a look at the vast number of examples that are included with it.

Full documentation, including a step-by-step tutorial, is available on the Webbino wiki.
