🦖 Webcam Powered Dino Alert Electronics Project (CHM)

In this fun, beginner-friendly project, you’ll build a system that uses your laptop’s webcam to detect motion and trigger a hilarious “Dino Alert!” on screen. When movement is detected, a T-Rex appears, opens its mouth, waves its tiny arms, and warns everyone nearby with a roar.
No prior experience is required. By the end, you’ll have a working Dino Alert system—and a solid foundation for building more advanced projects that combine software and electronics.

If you have a laptop, please bring it — but come anyway if you don’t!
