Raspberry Pi For Beginners - 2022 Complete Course - Project - Step 1

The video tutorial covers setting up a Raspberry Pi to detect movement using a PIR sensor. It explains the logical structure needed to determine when movement is detected for three consecutive seconds, triggering a photo capture. The tutorial includes implementing a timer, handling GPIO cleanup, and using an LED as a visual indicator. It also discusses optimizing the code to prevent excessive photo captures and emails.
