 SimplePost messages to Twitter (tweet) from Aruduino with Ethernet Shield!

 Notice
 -The library uses this site as a proxy server for OAuth stuff. Your tweet may not be applied during maintenance of this site.
 -Please avoid sending more than 1 request per minute not to overload the server.
 -Twitter seems to reject repeated tweets with the same contenet (returns error 403).
