Finally, when it is over, we stop the connection. This is done with the following code:
if (!client.connected()) {
Serial.println();
Serial.println("disconnecting.");
client.stop();
}
We repeat the entire process every 10 seconds with the following line:
delay(10000);

It is now time to test the sketch and upload data to Xively. You can upload the sketch to
Xively at this point, and open the Serial Monitor in the Arduino IDE. You should see that
the IP address of the board is being printed out, and that the sketch is connected to the
Xively server:
IP address: 192.168.1.104
Connecting...
You should also see how the data was formatted for Xively:
{"version":"1.0.0","datastreams" : [ {"id" :
"Temperature","current_value" : "24"},{"id" :
"Humidity","current_value" : "37"}]}
After a moment, you should see the answer coming back from Xively. If the data was sent
correctly to the Xively server, you should see a
200 OK
code being printed out to the
Serial Monitor:
HTTP/1.1 200 OK
