Introduction: Railway Level Crossing
Automatic Railway crossing is a great and very interesting project. it is also very useful in level Crossing. In our project we are using two sensors for detect the position of Train. when train cross the IR sensor, Controller Circuit will close the gate and when train cross another IR sensor controller circuit will open the gate.
Two IR sensors are placed in both side of crossing when train come from one side it will interrupt the IR light, means sensor one is activated and arduino detect this changing and it will close the gate by giving the signal to L293D motor driver. but in next time when train cross the second sensor arduino will detect the this changing and open the gate by using L293D motor driver.
