This system uses PIC 16F877A microcontroller with the help of sensors. It can divide into two parts. The first part is concern on the hardware development where all electronic components have included. IR sensors, inductive sensors are the input components while buzzer, light indicator, DC motor and LCD display are the output components. The microcontroller forms the main unit of the system.The first inductive sensor and IR sensor are fixed at a certain distance from the gate and the second sensors are fixed at the same certain distance after the gate. The gate is closed, when the train crosses the first IR sensor and the gate is opened, when the train crosses the second IR sensor.
