Summary
Let's summarize what we achieved in this project. We saw how to implement M2M communications using the ESP8266 Wi-Fi chip. We illustrated this by building two simple projects that used IFTTT to make the link between the ESP8266 boards.
You can of course now use what you learned inside this project to build your own Machine-to-Machine projects. M2M communications is a very wide topic, and there are so many things you can implement with it. For example, you could build a complete security system based in the cloud, with just ESP8266 modules communicating with each other, each equipped with a motion sensor. This is something we are also going to see later in the book.
In the next chapter, we are going to again use IFTTT, but for another purpose: ...
