Internet of Things with Raspberry Pi 3

Summary

In this chapter, we learned about how the internet works; it is the backbone of communication. Why JavaScript and Node.js are becoming the favored choices for developing IoT applications. Then, we learned about HTTP and MQTT protocols thoroughly, implemented them using Raspberry Pi and servers, and demonstrated how communication happens between two machines.

In Chapter 4, Weather Station, we will build our first project, a weather station, using Raspberry Pi and multiple sensors.
