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 Visitor Counter automatically counts the number of people entering or leaving a room using an IR sensor. The count is displayed on a 16×2 LCD, and a buzzer can alert when a specific limit is reached. This project is widely used in shops, libraries, offices, and events to monitor occupancy. It demonstrates sensor interfacing, counting logic, and real-time display using Arduino.

A digital ruler is an electronic measuring device that provides precise measurements of length, width, or depth. Unlike traditional rulers or tape measures, digital rulers use sensors and electronic displays (often LCD or LED) to show measurements accurately, usually in both metric (mm/cm) and imperial (inches) units. They are widely used in engineering, design, woodworking, tailoring, and education where precision is critical.
