Magnetically-Activated Escape Room Prop Tutorial - Sensor Selection and Arduino Implementation

Learn how to create magnetically-activated escape room props in this comprehensive 44-minute tutorial. Explore the use of magnetic sensors as input devices for escape room tech puzzles, including Hall sensors and reed switches. Discover how to select appropriate magnets and sensors, analyze component datasheets, and compare the output and sensitivity of various magnetic sensors. Follow along with practical demonstrations and Arduino code examples to build an all-purpose magnetic prop controller that automatically calibrates, offers adjustable sensitivity, and responds to both north and south poles of magnets. Gain valuable insights into creating "magical" interactive elements for escape room experiences, from simple book placement puzzles to complex chessboard challenges.
