Common Room Tracker

A simple Arduino-based device to help students track the occupancy of hostel common rooms in real-time.

Project Description

When students move between hostels, they often waste time and energy carrying luggage while searching for vacant common rooms. This project solves that by providing a small device that counts students entering a common room and displays live occupancy status.

Each device:

• Uses a pushbutton (or sensor) to count students.
• Displays the current count and room status (Open, Rush, Closing Soon, Full) on an LCD.
• Helps students and staff manage room capacity efficiently.

How It Works

• Pushbutton: Each press adds one student to the count.
• LCD Display: Shows current student count and status.
  • 0–69 → Open
  • 70–89 → Hurry Up!
  • 90–99 → Closing Soon
  • 100 → Full (closed)

Materials Used

• Arduino Uno Rev 3 (or ESP32 for Wi-Fi version)
• 16x2 LCD Display
• Pushbutton switch
• Resistors (220Ω, 10kΩ)
• Breadboard & jumper wires

Code Overview

• Written in Arduino C++ using the LiquidCrystal library.
• Debounce logic ensures accurate counting.
• Display auto-updates with each press.
