Raspberry Pi For Beginners - 2022 Complete Course - Activity 09 - Create a New Python Script from the Terminal

This tutorial guides students through using the terminal and Python to work with files and sensors. It covers creating a new Python file by copying an existing one, modifying it to fix GPIO cleanup issues using try-except blocks, and executing the updated program from the terminal. The lesson emphasizes the importance of proper GPIO cleanup to avoid safety issues and warnings.

Describe the purpose of the PIR sensor in the context of the activities discussed.
