Chapter 2. First Projects with the ESP8266

Now that your ESP8266 chip is ready to be used and you can connect it to your Wi-Fi network, we can build some basic projects with it. This will help you understand the basics of the ESP8266.

We are going to see three projects in this chapter: how to control an LED, how to read data from a GPIO pin, and how to grab the contents from a web page. We will also see how to read data from a digital sensor.
