Motion-Triggered Christmas Projections (Holiday Magic!)

This tutorial walks through building motion-triggered holiday projection effects using a projector, a media player, and a motion sensor. When a passerby triggers the sensor, pre-loaded visual effects — including a roaming reindeer, a growing doorway garland, and a gift-box reveal — play back automatically. The setup is suitable for both indoor and outdoor use and is presented as approachable for beginners. Downloadable effect files are available through the creator's website.
