DIY Password-Protected Smart Security Kit | Smart Electrical Safety Project Using Arduino

The DIY Password-Based Circuit Breaker Kit is a hands-on electronics learning kit designed to demonstrate electrical safety and automation control using an Arduino microcontroller. This project allows users to control electrical appliances (like bulbs, fans, etc.) by entering a password through a keypad, ensuring that only authorized users can operate the system.

The system works by inputting a password on the 4×4 matrix keypad; once verified, the relay module activates the circuit, powering the connected load. If the password is incorrect, the circuit remains off, ensuring safety and restricted access.

This kit is ideal for students learning about Arduino programming, relays, automation, and embedded security systems.
