/*
Arduino --> ThingTweet via Ethernet
The ThingTweet sketch is designed for the Arduino + Ethernet Shield.
This sketch updates a Twitter status via the ThingTweet App
(http://community.thingspeak.com/documentation/apps/thingtweet/) using HTTP POST.
ThingTweet is a Twitter proxy web application that handles the OAuth.
Getting Started with ThingSpeak and ThingTweet:
* Sign Up for a New User Account for ThingSpeak - https://www.thingspeak.com/users/new
* Link your Twitter account to the ThingTweet App - Apps / ThingTweet
* Enter the ThingTweet API Key in this sketch under "ThingSpeak Settings"
Arduino Requirements:
* Arduino with Ethernet Shield or Arduino Ethernet
* Arduino 1.0 IDE
* Twitter account linked to your ThingSpeak account
Network Requirements:
* Ethernet port on Router
* DHCP enabled on Router
* Unique MAC Address for Arduino
