ABSTRACT
Our project aims at a railway level crossing gate opening/closing system operated throughan android application The opening/closing of railway gate is traditionally operated through manual lever pullingmethod.This application just any android OS based device to run on. A Bluetooth device attachedto the railway gate is used to receive the Bluetooth commands.These commands are then passed on to an Arduino microcontroller which then performsthe required action. On receiving opening command, it drives the motors to open thegate and closes the gate on receiving the close commands. It does this by driving themotor through a driver IC to achieve this functionality.

1. Arduino microcontroller
Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button.
