 This sketch emulates a Philips Hue bridge running on an ESP8266 using the Arduino IDE. Right now this is a proof-of-concept; contributions are highly welcome. Hue client apps can [discover](../../wiki/Discovery) the emulated bridge and begin talking to it using the Hue protocol.

-__Optionally__, vou can use a strip of individually addressable WS2812b NeoPixels and attach it to GPIO2. The sketch talks to a strip of NeoPixels connected to GPIO2 of the ESP8266 with no additional circuitry. Right now the sketch uses the NeoPixels to tell that it is powered on, connected to the WLAN etc., and can switch on the first 3 NeoPixels using a Hue client (e.g., the iOS app).
+__Optionally__, vou can use a strip of individually addressable WS2812b NeoPixels and attach it to GPIO3. The sketch talks to a strip of NeoPixels connected to GPIO3 of the ESP8266 with no additional circuitry. Right now the sketch uses the NeoPixels to tell that it is powered on, connected to the WLAN etc., and can switch on the first x NeoPixels using a Hue client (e.g., the iOS app). Currently only first version of the app is working. The number of NeoPixels that work depend on the amount of memory made available in the buffer. Currently 4096 means 14 NeoPixels can work. (See comments below)
 
 To make this work, the sketch advertises its service with the so-called "Simple Service Discovery Protocol" (SSDP) that is also used as discovery protocol of Universal Plug and Play (UPnP). This sketch uses the ESP8266SSDP library from https://github.com/me-no-dev/Arduino
