Summary

We have seen that two electronic devices can use the internet to interact with each other and exchange information, without the need for a direct physical connection between them. Nodes can be interfaced with other objects and cloud applications and this architecture allows the implementation of smart solutions in different markets and with huge benefits for users.

We’ve seen the architecture of an IoT solution, the different telecommunication technologies, and the security aspects involved.

We have talked about methods to protect your intellectual property against the duplication of your product and how to adopt open source libraries without the need to release your source code.

Finally, please respect the Arduino trademarks when implementing a commercial solution based on the Arduino ecosystem.

All this information is necessary to understand how things behind an IoT application work and for you to consider the right approach for your next IoT solution.

Before stepping into the next chapter, with the first example of an IoT project based on the Arduino IoT Cloud, it’s worth recapping the main steps to engineer a good IoT solution:

1. Identify the application and define the business model.
2. Determine the requirements and goals of the IoT application.
3. Identify on the edge versus on the cloud and structured code versus AI/ML model requirements.
4. Select the most appropriate telecommunication technologies.
5. Choose the appropriate hardware for the IoT node.
6. Select the provisioning mode according to the size of the project.
7. Develop the software for the node and configure the cloud, as we’ll see in the following chapters.
8. Deploy the application and periodically monitor performance and security.
