In this 2-part lecture I will show you how to get your Arduino gadget to speak to the Internet! In part 1, I showed you how to connect your Ethernet shield, and how to make your Arduino part of your local network. I also showed you how to connect to the network by automatically acquiring an IP address via DHCP, or how to acquire an IP address manually.
In this 2nd part, I show you how to turn on and off an LED, and to read light intensity through a Telnet connection to your Arduino from your computer.
