Serving a Web Page
Just as the Galileo can contact a web server to get or post information, it can
also act as a simple web server itself. You can use your web browser to con-
nect to it and get information about its input pins (such as sensors you've
connected) or have it actuate an output when a browser connects. To test
out these capabilities, you're going to have a web page update when a button
is pressed.
1. Just as you did in
Figure 4-2
, wire up a button to pin 2 of the Galileo.
2. Connect the Galileo to your network via Ethernet.
3. Create a new sketch with the code from
Example 6-10
and upload it to
your board. This example is based on the Arduino example found in File

WebServer.
4. Open the serial monitor to see the IP address that was assigned to your
Galileo by your router.
5. Open a web browser, enter that IP into the address bar, and hit Enter.
You should see the following text on screen: “The button is not pressed!” Try
pushing the button and hitting refresh on your browser. You should then see
“The button is pressed!” (
Figure 6-7
)
