/* HueBlink example for ArduinoHttpClient library

   Uses ArduinoHttpClient library to control Philips Hue
   For more on Hue developer API see http://developer.meethue.com

  To control a light, the Hue expects a HTTP PUT request to:

  http://hue.hub.address/api/hueUserName/lights/lightNumber/state

  The body of the PUT request looks like this:
  {"on": true} or {"on":false}

  This example  shows how to concatenate Strings to assemble the
  PUT request and the body of the request.

  note: WiFi SSID and password are stored in config.h file.
  If it is not present, add a new tab, call it "config.h" 
  and add the following variables:
  char ssid[] = "ssid";     //  your network SSID (name)
  char pass[] = "password"; // your network password
