== ESP8266 or ESP-01 ==
There are a lot of different modules [http://www.esp8266.com/wiki/doku.php?id=esp8266-module-family ESP-NN]. In this tutorial we will use the ESP-01 which is by far the cheapest (1,5€). It only exposes two io pins but we only need 1 or 2 depending if we want to have an additional sleep timer for shutting down the lamp.
The flash chip has 512k from which 64k can be used as a file system for all the files we want to serve. The ESP-12 for example has 4MB flash.
