Automatic Railway Crossing System with IR Sensors, a simulation project designed to replicate the operation of railway crossings using infrared technology. ThisĀ  project uses IR sensors, Arduino NANO, servo motors, a train model, rechargeable battery, LM7805 voltage regulator, electrolytic capacitor, and DC connectors. Ideal for students, educators, and railway enthusiasts, this system provides a hands-on experience in understanding automated railway safety mechanisms.

Key Features:

  • Railway Crossing Simulation: Mimics the operation of real railway crossings for enhanced learning.
  • Automatic Operation: Automatically closes and opens the railway barrier based on train detection.
  • Educational Tool: Perfect 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 railway safety systems.

Components Used:

  • IR Sensors: Detect the presence of an approaching train.
  • Arduino NANO: Controls the operation of the system based on sensor inputs.
  • Servo Motors: Mechanically operate the railway barrier to close and open.
