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 Water Level Indicator is an electronic device used to detect and display the level of water in a tank or reservoir. It helps prevent overflow and dry running of pumps by giving alerts or showing water levels in real time.

An XOR (Exclusive OR) gate is a digital logic gate that outputs true (1) only when the number of true inputs is odd. For two inputs, the output is high when the inputs are different. XOR gates can be constructed using basic logic gates or directly with transistors (BJT or MOSFET). Using transistors, we can design compact, efficient circuits for custom digital logic applications.
