Design and Construction of Movable Bridge using Arduino

This paper is designed to build movable bridge for passable both land and marine transportation and upgrade transportation system for people. In this paper, Arduino Uno, ultrasonic sensor, servo motor, 2channel relay and gear motor are used as mainly devices. Ultrasonic sensor is running by emitting waves until the ship is coming. As soon as the ship is passing, the sensor is sent data to arduino. And then, arduino microcontroller control the traffic light on the land by changing green led to red led. In this condition, the servo motor start to run and gate on the land is closed. After gate is closed, the gear motor start to run and lift the bridge to cross the ship. When the ship is passed, the bridge down to normal state and red led change to green led. When the led is green, the servo motor start to run and gate is open. At this time, the cars can pass safety.
