How do I figure out how to connect to my arduino using ethernet shield?
It prints the IP in the serial monitor, but it doesn't work, and adding the port doesn't make a difference.
The client example works, so it's not broken or anything.
I'm using Arduino 1.6.5 IDE on a Mega 2560. I'm trying to run the Examples/Ethernet/WebServer example.
Your question is kind of trivial, but from what I understood you're typing the IP address (that the Arduino displays on the serial monitor) into your browser.
First, make sure you connect your Ethernet shield to your router using an ethernet cable. (Now it's connected locally...)
Second, even if you type in your Arduino's IP address into the browser, the browser will return nothing because the Arduino simply has nothing to display, and hasn't been programmed to accept requests.
To actually have the Arduino display something you can try the Webserver example sketch or you can follow this great Tutorial that I found very useful for beginners.
BTW ports are only used to expose your Arduino to the Internet, in other words if you don't portforward to your Arduino, your Arduino won't be able to get requests from outside your local network (Wi-Fi,Ethernet).
It prints the IP in the serial monitor- I'm not asking you to describe what you see. Please copy and paste it. What IP addresses are you using on your local LAN? For example, do you see a message like "new client"? – Nick Gammon♦ Aug 25 '15 at 2:22
