The ROBODIUM Magnetic Door Alarm Kit is a beginner-friendly DIY security system designed to detect door or window openings using a MC-38 magnetic switch sensor.
When the magnet is separated from the switch, the sensor triggers the Arduino Uno, which activates LEDs or an external alarm.

This kit is ideal for:
Home security
School/college electronics projects
Smart door systems
DIY alarm setups
STEM learning

With simple wiring and fully reusable components, anyone from beginners to hobbyists can build a working door alarm system in minutes.
