it took some time but finally the Arduino Uno is doing what he was supposed to do:
- Go to Twitter
- Look if there is a new tweet with the word "morse"
- Get the tweet
- Translate the tweet to morsecode
- Give the morsecode as an acoustic signal
Now there are cw-signals in my room and I don't have to look at the computer screen. You find details in my blog: http://hajos-kontrapunkte.blogspot.com/2011/01/morsetweeter-v-07-is-running.html
Of course the project is not finished. The parser for the HTML-Code has to be optimized, ... The LCD-shield has to be connected and later the Arduino will controll a real morse keyer. Then the code will be published. Stay tuned!
