sudo python3 sample/buzzer.py
PS: 1. The above sample python file maybe depends on the third-party python library `Rpi.GPIO`. In the official Raspberry Pi OS and most third-party OS, this library is installed by default. If you run this file and get some errors, try to run the following command to install the Rpi.GPIOy library.
sudo apt-get install -y python3-smbus python3-rpi.gpio
Or you can refer to [[How to Install RPi.GPIO Python Library]]
2. The sample program is only to demonstrate how to use the advanced functions of the shield, we do not provide the development function of the sample program.
