sudo python3 sample/buzzer.py
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]]
