Enables your Arduino board to access the Internet via an Ethernet connection using the Wiznet W5100 Ethernet Chip. Based on the Wiznet W5100 Ethernet Chip, it provides a straightforward way to bring online connectivity to your Arduino projects. Compatibility: Compatible with Duemilanove boards (168) and Mega 1280/2560, and can be accessed using the standard Ethernet library. Form factor and fit: Standard Arduino shield form factor that fits all shieldcapable Arduino main boards. Build and materials: Compact shield PCB designed to mount on of compatible Arduino boards for reliable connections. Performance and reliability: The W5100 chip handles the Ethernet TCP/IP operations, enabling stable network communication for Arduino projects. Use scenarios: Remote sensor data logging: connect sensors to the Arduino and send data to a web service or cloud database. Remote configuration and control: retrieve configuration data from a server or trigger actions via HTTP requests. Local network monitoring: provide a simple web interface or status page on a local LAN for basic monitoring.
