Arduino based rss reader is an enhanced integration between Arduino and Internet connection. This project using python to read the feed and send serially to Arduino then display on LCD. This project could be expanded to use with any website that has rss feed service such as read your facebook status, stock quotes, weather report, or twitter status. [link]
Here is a great Arduino project for Twitter users. Arduino reads ambient temperature then sending mean value for displaying on Twitter . This project using Arduino Duemilanove, Arduino Ethernet Shield, three temperature sensors(LM35) [link]
Twitter again, this is more fun for Twitter users. The farther you are away from the computer, the larger the text and the greener the screen. Otherwise, the text becoming smaller and redder the screen, if you getting closer to the computer, It is use Maxbotix LV-EZ2 ultrasonic range-finder , arduino diecimilia and buzzer.
arduino & sonar returns your distance away from the computer and it is displayed on the screen. the farther away you are from the computer the larger the text and the greener the screen. the closer you are, the smaller the text and the redder the screen. get within 5 inches and a buzzer alarms. distance is twittered.
Nowadays Arduino based project that connects to Twitter is a hot project. Here is an example by Bruno Soares.
Hardware Twitter is a project that uses the Arduino board and a LCD display to display messages from Twitter. For the Arduino has messages written in a software Adobe AIR / Flex, which connects to the Serial Proxy sending content to the Arduino.
Boobie the Tweet Bird is a project for Multimedia in Artistic Environments.
we have a rude processing application reading the rss feed coming from Twitter, and everytime a new message arrives from the ones you’re following, the app sends a signal to Arduino, and the bird sings
