Project Idea:
This project is designed to enhance safety for electrical line workers by allowing them to directly control the electrical circuit through a password-based system. It prevents accidents caused by miscommunication between linemen and substation staff during maintenance work. The circuit can only be turned ON/OFF by entering the correct password on a matrix keypad, making the operation secure and manual from the lineman's side.

8051 Microcontroller
Matrix Keypad
LCD Display
Relay Driver IC
Voltage Regulator IC
EEPROM IC (for password storage/upgrade)
