I've been trying to post a tweet through Arduino, I tried NeoCats library (http://arduino-tweet.appspot.com/) and I tried Markkurossi's library (http://www.markkurossi.com/ArduinoTwitter/) Neither of them worked for me, I'm new to Arduino, could you give me a sample code that worked for you? My ethernet connection went through, I made an account through dev.twitter.com, but I just can't seem to get a connection going through.
I also have the same problem. It seems to be an issue with both libraries. Is there another library we can download for a reliable connection to twitter? or is there a specific code we need for NeoCat's and/or Markkurossi's libraries?
It will be very hard to send a tweet from the Arduino board.
You can use a service like https://thingspeak.com/ and use that to post a message to twitter.
Just tried it. Worked fabulously. 8) Would recommend it.
Another service is OAuth. http://playground.arduino.cc/Code/TwitterLibrary
