 simpleTweet_00 arduino sketch (for use with

 simpleTweet_00 processing sketch) by @msg_box june2011

 This script is intended for use with a magnetic reed switch,

but any on/off switch plugged into pin #10 will readily work.

The Arduino is connected to a circuit with a sensor that

triggers the code: Serial.write(n); where n = 1 or 2.

The Processing sketch listens for that message and then

uses the twitter4j library to connect to Twitter

via OAuth and post a tweet.

To learn more about arduino, processing, twitter4j,

OAuth, and registering your app with Twitter...

This code was made possible and improved upon with

help from people across the internet. Thank You.

Special shoutouts to the helpful lurkers at twitter4j,

arduino, processing, and bloggers everywhere, and

to the adafruit & ladydada crowdsource.

And above all, to my lovely wife, without

whom, none of this would have been possible.

Don't be a dick.
