Enabling Communication between Different Devices

This chapter is dedicated to thing-to-thing communication (TTC), which is a very important concept and requirement in the field of the Internet of Things (IoT). You can also call it Device-to-Device (D2D) communication. D2D communication plays a vital role in complex systems where one device’s operations are totally dependent on another device. For example, say you want to control your room’s AC according to outdoor weather conditions; here, D2D communication plays a vital role by sending the outdoor temperature to the room’s AC controller device so it knows whether it needs to cool or heat the room according to the weather outside.

Arduino IoT Cloud provides a cloud variable synchronization feature across multiple things, as well as for dashboards, which helps us to build complex systems easily. This chapter explains the usage of the synchronization feature for the implementation of cloud graphical user interfaces...
