Vibration Detection System
A Vibration Detection System using Arduino, a vibration sensor, and a buzzer that triggers a sound alert when vibrations or movements are detected.
Description
The Vibration Detection System is designed to detect vibrations or movements using an Arduino and a vibration sensor. When the vibration sensor detects any movement or shock, it sends a signal to the Arduino. The Arduino processes this signal and activates the buzzer to produce a sound alert. This system can be used for security or monitoring applications, such as detecting unauthorized access or structural vibrations.

A Digital Lock System is an electronic security project designed to control access using a password entered via a keypad. It utilizes an Arduino, keypad, LCD, servo motor, and buzzer to provide a safe, automated locking mechanism. When the correct password is entered, the lock opens; if the wrong password is entered, an alert is triggered. This project is widely used in home security, lockers, safes, and access-controlled systems.

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
