Do you want to make a web-enabled on / off switch for that power hungry RAID array living in your closet? Or maybe you want to build your very own version of the Twittering Cat Toy? Then you should check out the Arduino Ethernet Shield from the Maker Shed! It’s the perfect solution for creating network enabled projects and it plugs right into your Arduino Uno, Mega, or compatible microcontroller. The on-board Wiznet W5100 Ethernet chip handles the heavy lifting and the completely open source Ethernet library makes it easy to write sketches that connect to the internet. This versatile shield even includes a micro-SD card reader that can be used to serve files over the network. Brilliant!
