Summary
In this chapter, we realized our first basic projects using the ESP8266 Wi-Fi chip. We first learned how to control a simple output, by controlling the state of an LED. Then, we saw how to read the state of a digital pin on the chip. Finally, we learned how to read data from a digital sensor, and actually grab this data using the aREST framework which we will use in several chapters of this book.
In the next chapter, we are going to go right into the main topic of the book, and build our first Internet of Things project using the ESP8266.
