Connecting the Wi-Fi module

In this case, the Wi-Fi module is the CC3000 shield. Shields are basically ready-to-go modules that can be directly attached to the Arduino with any extra wiring. This makes them quite convenient to use. In this section, you will learn about connecting the Arduino to your home Wi-Fi network and linking it to the Internet.

The CC3000 Arduino shield

This shield is a relatively new means of communication for Arduino. The CC3000 chip is made by Texas Instruments, with the goal to simplify internet connectivity for projects such as the one we are going to make in this and the following chapter.

Connecting the shield to the Arduino is probably the simplest task in this entire book. Make sure the male header pins of the shield align with the female header pins of the Arduino board (UNO or MEGA), and then gently mount them together. You will have something like this:
