Sending data to a server
It is now time to build the sketch for our first application using the Arduino Ethernet shield.
But first, we need one more piece of data: the local IP address of your computer. Inside the
Arduino sketch, we are going to specify where the Arduino Ethernet shield has to send the
data.
Finding your IP address is easy, but it depends on your operating system. If you are using
OS X, you can find your IP address inside
Network Preferences
.
If you are using Windows, you will find the information you need under the
Network Set-

Another way under Windows is to go to
Start
, then
Run
, and type
cmd
. Then, inside the
console, type
ipconfig
and hit
Enter
. Your computer's IP address will be displayed.
If you are using Linux or OS X, you can simply go to a terminal and type:
ifconfig
This command should print your IP address inside the terminal window. It will in general
be something like
eth0
or
en0
. This is what I had on my machine:
