Mini/Micro projects
-
A Soil Moisture Detection System using Arduino, a soil moisture sensor, and a buzzer that sounds an alert when soil moisture is detected.
-
A Traffic Light Signal is an electronic project designed to manage vehicle and pedestrian traffic at intersections. Using Arduino, LEDs (Red, Yellow, Green), and an LCD, the system simulates real-world traffic light behavior, displaying signal changes with appropriate timing. This project demonstrates traffic management, embedded system programming, and microcontroller-based automation.

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.
