Micro:bit Trip-Wire Burglar Alarm Kit - STEM Learning for Young Makers

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Build a real working burglar trap that raises an alarm the moment a sneaky intruder breaks the invisible thread. This kit turns a classic spy gadget into a hands-on lesson in how sensors, code, and electronics work together. No prior experience needed - just curiosity and a hunger to create something that actually does something cool.

What You'll Build

A trip-wire alarm using conductive thread as a hidden sensor. Snap the thread and the micro:bit triggers flashing LEDs, a buzzer, and logs the time on its display. Perfect for guarding your room, a door, or your secret hideout.

What You'll Learn

• How digital input pins detect a circuit break - just like a real security sensor
• Writing if-else logic in MakeCode to trigger actions when the thread snaps
• Using a piezo buzzer to create custom alarm tones
• Logging events with the micro:bit's onboard clock to know when the trap was tripped
