This project is about making a pressure switch. It is like a burglar alarm that produces sound when someone steps on the device. The main mechanism that works in it is the completion of a circuit. When a person steps on the elephant’s face, the circuit underneath it gets completed and the buzzer beeps. It can be used outside a room under the floor mat and it will alarm you if someone enters your room without knocking.
The girls in fourth grade had a lot of fun sharing their creation with Kirandeep, our Academic Principal, and Jugat Guru Singh, the Head of School. Enjoy the video where you will get the chance to see how it works.
