3 Nanode

Nanode is designed to work like an Arduino, but is made specifically for Internet-connected projects. It features the same ATmega328 processor that the Arduino Uno uses, and you can program it with the Arduino IDE. Nanode uses the open-data API Cosm to connect to the Web for tasks including sending data to the cloud, following online feeds, or acting as the server for a small, simple website. It makes a good development tool for Web-connected sensors, monitors, or controls. The Nanode RF sells for $56.57, a higher price than Arduino. And some assembly is required, so get your soldering iron ready.
