Summary
What have we learned in this project? Firstly, we learned how to connect a temperature sensor to the STM32 Blue Pill microcontroller board. We then wrote the code to read the temperature and send it to our microcontroller. Subsequently, we learned how to connect a Wi-Fi module to our STM32 and code a sketch to connect the board to the internet.
This project has given us the skills to begin to create an IoT application, a great skill in this hyper-connected world. In the forthcoming chapters, you will be able to apply what you have learned since they consist of projects that require an internet connection. In Chapter 10, IoT Plant Pot Moisture Sensor, you will learn about measuring the moisture of a pot through a sensor and sending it to the cloud. We will visualize the sensor data on a web page.
