SR ROBOTICS Password based circuit breaker using ardino Educational Electronic Hobby Kit

The Password-Based Circuit Breaker is an electronic security system designed to control the flow of electricity in a circuit using a password authentication mechanism. This system ensures that only authorized users can switch ON or OFF an electrical load, enhancing safety and preventing unauthorized usage of electrical appliances. In this project, an Ardino microcontroller acts as the main controller. A keypad is used to input a password, and an LCD display can show the status of the system (e.g., "Enter Password", "Access Granted", "Access Denied"). Once the correct password is entered, the Arduino activates a relay module that controls the flow of current to the connected load. If the wrong password is entered, the system denies access and can trigger an alert. This project can be implemented for home or lab appliances to add an extra layer of security and prevent unauthorized power usage.
