Description:
Want to make your own Tweet-a-Watt or Botanicall that posts data to a Twitter account for you to follow? In this class, we'll play with the Arduino Ethernet Shield and look at how to connect to remote servers. We'll build a simple project that will take button press data and post it to a Twitter account from the Arduino device using HTTP. We'll go over the basics of Ethernet, TCP/IP, and the HTTP protocol. Materials students will need: - Laptop computer that can run the Arduino IDE - Arduino shield-compatible development board - Ethernet cable - Arduino Ethernet shield using the Wiznet interface -- here's some sources, or you can buy it along with your class pass $40: http://www.nkcelectronics.com/arduino-ethernet-shield.html $30 with some soldering: http://www.nkcelectronics.com/nkc-ethernet-shield-for-arduino-mega--duemilanove--diecimila-diy-kit.html $15, requires separate Wiznet module: http://www.adafruit.com/index.php?main_page=product_info&cPath=17_21&products_id=83
Students will go home with this board, which includes an LCD!

Note: the adafruit and nkcelectronics shields won't work well with the LCD/button shield we're using in the class because of board height problems :( The original Arduino Ethernet shield works, but you'll need some electrical tape around the Ethernet jack to prevent shorts.
