Summary
In this chapter, we discussed the basics of IoT, including its main characteristics that distinguish it from other technologies, and we discussed the architecture of IoT and learned the directions of data flow and control flow in the IoT architecture. Then, we explored some common and popular applications of IoT such as smart homes, healthcare, industrial automation, transportation, logistics, and agriculture.
After discussing IoT, we discussed the ESP32 board, compared it with other microcontrollers, and discussed the different variants of ESP32 boards and how ESP32 can be programmed. We then discussed the Arduino IDE 2.0, which is the latest version of the Arduino official board programmer, installed the ESP32 board support to set it up for using ESP32, and finally, we ran a “Hello World” example on ESP32 and simulated it using an ESP32 simulator, which can help us in cost savings, testing, and debugging.
In the next chapter, we will be discussing how to interface sensors with ESP32.
