Automatic Railway Gate Controller with a High-Speed Alert System The automatic railway gate control system automatically controls the operation of railway gates by detecting the arrival and departure of trains at the gate. Detectors are placed at a faraway distance on a railway track to detect the arrival and departure of a train. Detectors are connected to a microcontroller, which activates the motor to perform the mechanical action of opening and closing the railway gate. The main aim of this project is to operate and properly control an unmanned railway gate to avoid accidents at the unmanned railway crossing. The following project is designed to overcome the accidents that have become common in our day-to-day life, particularly at the railway crossing gates. This project consists of four IR LEDs, and the Photodiodes are placed on either side of the track. Initially, the IR LED is the transmitter that continuously transmits IR light and allows it to fall on the receiver. When a train arrives, it blocks the light falling on the receiver. Let us consider that the train is moving from left to right and the first sensor pair acts as a counter and gets activated when the train blocks it, and then the second sensor pair stops working as a counter. The counter values generated here are used to calculate the velocity of the train. The out of sort sensor 2 is sent to the microcontroller, which in turn makes the relays active, and then the gate gets closed. When the train blocks the last carriage of the track then the relays get deactivated and the crossing gate is opened. This project is programmed in such a way that it is advantageous in calculating the velocity of the train. If the speed of the train exceeds its limit, then the passengers are alerted by activating a buzzer as an indication that the train is moving at over speed. 12). 8051 Microcontroller based Electronic Locker System Nowadays security is a major problem for houses, banks, and jewelers due to an increase in cases of robberies owing to insecure systems. To overcome this problem, this article demonstrates the implementation of a microcontroller-based electronic locker system to resolve this problem. An electronic lock is a device that has an electronic control assembly attached to it and is provided with an access control system.

The LCD and Switches are given as input and output to the microcontroller. The LCD data pins are connected to the port1 pins of the microcontroller, and L293D is used to rotate the motor bidirectional for opening and closing the door. A microcontroller-based door lock is an access control system that allows authorized persons to access a restricted area. The system has a keypad for entering a password. If the password entered is correct and matches the password stored in the microcontroller, then the door gets opened with the help of the motor. If the password entered comes as wrong after attempting it thrice, then the alarm gets switched on. 13).

This project is intended to save the ground space required for parking. By using this system, a huge number of cars can be parked according to the requirement, on floors that are one above the other. In this car parking system, there is an IR transmitter and receiver for the parking slot. IR receivers are connected to the microcontroller. Whenever a car is parked in the parking slot, the IR rays are obstructed, and the microcontroller comes to know which slot is empty and which slot is occupied, and then displays the result on the LCD. Furthermore, Light-emitting diodes are used as an indication for showing the empty slots. LEDs are placed at the entrance of the parking slot to minimize human interference for monitoring car parking. In this circuit, the sensors are replaced by the switches and are connected to the port 1 of the microcontroller. Whenever a car parking slot is filled, the switches turn on and the LEDs glow as an indication to show the unoccupied slots and the LEDs turn off to show the parking slots that are filled. The LCD is connected to the port 3 of the microcontroller and the parking status is sent to the microcontroller to make it being displayed on the LCD.
