## Article

Sample : Serial port => Twitter gateway
Run this program on Arduino and connect via some Serial port terminal software.
Type a message and hit enter key, and it will be posted to Twitter.
Arduino IDE Serial Monitor is not usable because it doesn't seem able to send Enter key code.
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).
