Sending power consumption data to Xively

Let's now build the sketch that will upload the power measurement data to Xively. The sketch is based on a test sketch, so I will only detail the new parts. We will now go through the most important parts of the code for this section. To get the complete code, please refer to the GitHub repository of this chapter.

It starts by importing the correct libraries:

#include <Adafruit_CC3000.h>
#include <SPI.h>

We then need to define the pins of the CC3000 chip:

#define ADAFRUIT_CC3000_IRQ   3
#define ADAFRUIT_CC3000_VBAT  5
#define ADAFRUIT_CC3000_CS    10

After that, we need to declare the CC3000 instance:

Adafruit_CC3000 cc3000 = Adafruit_CC3000(ADAFRUIT_CC3000_CS, ADAFRUIT_CC3000_IRQ, ADAFRUIT_CC3000_VBAT, SPI_CLOCK_DIV2);

Now, this is the part where you need to enter your information. First, you enter the SSID and the password of your local Wi-Fi network:

#define WLAN_SSID       "yourSSID"
#define WLAN_PASS       "yourPassword"
#define WLAN_SECURITY...
