Visitor Counter with Automatic Door, an innovative project designed to count visitors and automatically control a door mechanism. This project uses an Arduino UNO, IR sensors, an LCD display, a single channel relay module, an L293D motor driver, a motor for the door, and a DC adapter. Perfect for students, educators, and hobbyists, this system offers hands-on experience with automation, sensor integration, and Arduino programming.

Key Features:

  • Visitor Counting: Accurately counts and displays the number of visitors.
  • Automatic Door Control: Opens and closes the door based on visitor detection.
  • Educational Tool: Ideal for teaching principles of automation, sensors, and Arduino programming.
  • Complete Kit: Includes all necessary components for easy assembly and demonstration.
  • Hands-On Learning: Provides practical experience with electronics and automated systems.

Components Used:

  • Arduino UNO: The main microcontroller for processing inputs and controlling outputs.
  • IR Sensors: Detect the presence of visitors and send signals to the Arduino.
  • LCD Display: Shows the number of visitors counted by the system.
  • Single Channel Relay Module: Controls the motor for the door based on signals from the Arduino.
  • L293D Motor Driver: Drives the motor for the door, allowing for forward and reverse motion.
  • Motor for Door: Mechanically operates the door based on control signals.
  • DC Adapter: Provides power to the entire circuit.


  • Visitor Detection: IR sensors placed at the entrance detect visitors passing through and send signals to the Arduino UNO.
  • Counting Mechanism: The Arduino UNO processes these signals to increment or decrement the visitor count.
  • Display: The current visitor count is displayed on the LCD screen in real-time.
  • Door Control: Based on the visitor count and sensor signals, the Arduino UNO sends commands to the relay module.
  • Motor Operation: The relay module activates the L293D motor driver, which in turn controls the motor to open or close the door.
  • Power Supply: The DC adapter ensures a stable power supply to the Arduino and other components.


  • Educational Demonstrations: Perfect for classrooms to teach automation and sensor technology.
  • Student Projects: Suitable for science fairs and practical electronics assignments.
  • DIY Enthusiasts: Great for hobbyists exploring automation and Arduino projects.
  • Building Security: Can be adapted for use in real-world visitor counting and automatic door systems.
  • Prototyping: Useful for developing and testing new ideas in automated systems and visitor management.
