Add a sound effect to your project! The small wiring inside this buzzer sends current through a wire, which magnetizes a post that pulls on a metal arm. When the metal arm touches the post, it makes a tiny noise and immediately cuts the current, so the arm is released. This process repeats so fast that the metal touching and releasing from the post makes a BUZZ.
The Mechnical Buzzer Cube is just one part of a circuit. Add a battery to power your creations, a motor to make them move, an LED to light them up, and a switch to take control!
- Fits your bricks! Compatible with major brick brands
- Seamless circuit connectivity (no soldering)
- Safety-tested & approved for ages 8+
- Created by STEM teachers, tested by kids
