1. Select the independent device

2. Copy the generated key. Use in the code.

3. Return to the device and click the three dots in the upper right corner

4. Select the interface configuration

5. Copy the following content into the box and click Update Configuration

Open Arduino and import the shared code

Replace the copied key into the first line of quotes

Replace the second and third lines with the name and password of your mobile hotspot

Then click compile

The following situation indicates that the compilation is successful and the code has no errors

Finally, burn the program into the microcontroller

Note: When burning the program to the microcontroller, the servo cannot be connected to the microcontroller, otherwise the programming will not be successful.

Note: Select the 2.4GHz frequency band instead of the 5GHz frequency band for the mobile hotspot AP band, otherwise the ESP8266 will not be able to connect to the mobile hotspot network.

The method demonstrated in this article is more suitable for students who just want to learn about the Internet of Things. If you want to learn more about it, it is recommended to start with the use of C language and Arduino, as well as the mechanism and pin usage of IoT microcontrollers such as ESP8266 and ESP32. Nowadays, there are many mature electronic modules on the market for us to use, which greatly reduces our learning costs. We can also use MiSiQi or Arduino graphical programming to complete our projects, further reducing the tedious time of entering codes.

Finally

I only regard the Internet of Things microcontroller as an interest and will not study it in depth. I only use this blog to record my learning, and also provide my own experience for students who want to understand the Internet of Things. I hope every electronics enthusiast can walk on the road of love.
