Digital code Lock System
A digital code lock system with a buzzer and servo motor is an embedded project that enhances security. When the correct code is entered, the microcontroller triggers a servo motor to unlock a door or container. If an incorrect code is entered, a buzzer sounds as an alert.
Description
A Digital Code Lock System using the 8051 microcontroller is an embedded security project designed to control access based on a secret passcode entered through a keypad. The system is ideal for securing doors, cabinets, or any restricted area, and it operates by comparing the entered code with a pre-programmed password. If the correct code is entered, the system unlocks the mechanism, and if the wrong code is entered, it triggers an alert using a buzzer. This project provides a hands-on approach to learning microcontroller-based programming and interfacing with different components.

This project involves controlling a DC motor’s direction using an 8051 microcontroller, with a buzzer and LED indicating the motor’s rotation state. When the DC motor rotates forward, the microcontroller keeps the buzzer and LED off. However, when the motor is rotated in reverse, the microcontroller triggers both the buzzer and LED to turn on as a visual and audible indication of the motor’s reverse rotation
