In this chapter, we've learned about the idea of home automation in its crude form. We also learned about how we can control an electrical load using relays. Not only that, but also we learned how to develop a WPF application and implement the MQTT protocol. On the device end, we used a Node.js code to connect our device to the Internet and subscribe to certain channels using the broker and ultimately receive signals to control itself. In the Android side of the system, we have used an already available MyMqtt application and used it to both to get and publish data. However, we also covered the development of the Android application in detail and showcased the use of it in implementing the MQTT protocol to control devices.

In Chapter 4, Intel Edison and Security System, we are going to learn how to deal with image processing and speech processing applications using Intel Edison. Chapter 4, Intel Edison and Security System, will mainly deal with Python and the usage of some open source libraries.
