Project 35 - Magnet Code Segment "K-12 JUNO STEM KIT"

What You Can Build Using K-12 JUNO STEM KIT

In the "Magnet Code Segment" project, learners create a unique security-style lock using a reed switch and slide switch connected in series to control a 7-segment display. Both switches must be activated simultaneously—the magnet must trigger the reed switch AND the slide switch must be ON—to illuminate the display segment. This dual-switch combination demonstrates advanced circuit logic and security principles.

What You Can Learn

• Series Circuit Logic: Understand how multiple switches in series create an "AND" condition where all inputs must be active for the output to work.

• Magnetic Sensing: Explore how reed switches respond to magnetic fields, forming the basis of contactless switching technology.

• Security Coding: Learn how combining different types of switches creates more complex access controls and security systems.

Real Life Problem Solving

• Access Control Systems: Many security systems require multiple authentication methods—like keycard AND fingerprint—working together to grant access.

• Industrial Safety: Machinery often uses multiple safety interlocks, including magnetic sensors and manual switches, to prevent accidents.

• Smart Home Technology: Modern devices use combinations of sensors and manual controls to ensure proper operation and security.

Applications and Extensions

• Add more switches to create increasingly complex security codes and multi-factor authentication systems.
