2. Arduino Tutorial
2.1 Data download
Arduino information contains library files and project code ,please click to download for follow-up study.
Data download: Arduino
2.2 Software Download
Open the browser and search: https://www.arduino.cc/en/software, we will take WINDOWS system as an example to show you how to download and install.

You just need to click JUSTDOWNLOAD,then click the downloaded file to install it.And when the ZIP file is downloaded,you can directly unzip and start it.

2.3 Set Arduino IDE
Connecting the board to the computer.
1.Select the development board .

2.Select the development board serial port.
Note: After connecting the development board to the computer, other serial ports (such as COM3) may appear. Please do not select the COM1 port.

2.4 Add Library
Open the Arduino IDE, follow [Sketch] → [Include Library] → [Add .zip Library]. This method can only import one library file at a time. If the product has multiple libraries, please import them one by one following this process!
