The document describes an automatic railway gate control system using an Android application. It involves opening and closing level crossing gates remotely using a Bluetooth-connected microcontroller and motor. When the gatekeeper sends a command from the Android app, the microcontroller activates the motor to close the gate. An LCD display shows the gate status. The system aims to prevent accidents by removing human involvement and errors at level crossings. It also reviews other research on using sensors and RFID to automate unmanned level crossing gates.
