Summary

In this chapter, we covered all the necessary background information regarding the IoT technology and ESP32 as a hardware platform for developing IoT products.

To add value to our end users, we, as developers, should know the ground. It is not enough to come up with a solution; it has to be the right solution, which requires us to learn more about the technologies and tools available. When it comes to IoT technology, things may become more difficult because an IoT product has several components, starting from sensor/actuator devices to end user applications, allowing end users to interact with the solution. In this manner, learning ESP32 is an important professional skill to be acquired by an IoT developer.

Following the background information in this chapter, upcoming chapters are going to focus on how to use ESP32 effectively in our projects. With the help of practical examples and explanations, we will see different aspects of ESP32 for different use cases and apply them in the projects at the end of each part. We will begin by using sensors and actuators in the next chapter.
