Automatic Railway Crossing Using Arduino

This is a simple college project. It automatically turn off the railway gate when train arrival and after train departure.

Step 1: Collect the Material

1. Arduino UNO (Or other)
2. L293d motor driver ic or shild
3. Two IR sensor
4. one Dc geared motor 30 RPM
5. 12volt Power supply (SMPS)
6. A toy train
7. A cardboard (as base)
8. solder
9. hot melt gun
10. A buzzer
11. A wooden or plastic rod for gate
12. some wires, screws

Step 2: Fix the Material on Cardboard

1. fix the track on cardboard as shown in pic or in my youtube video, link shown below
https://youtu.be/1Oc5R_yByNw
you can fix this by using hot melt glue, screw, rubber strip.

2. fix the moter on cardboard as shown in pic by screw or rubber strip.

3. connect a plastic or wooden rod to motor's axis, this is used as gate.

4. fix two IR sensor in both side of gate(motor) and should be at equal distance as shown in my video

5. Remove the LED's from circuit of sensor and fix opposite to PHOTO TRANSISTOR and connect by wires

Step 3: Circuit Connection and Wiring

circuit diagram is shown in pic.
1. connect the IR sensor's Vcc and GND pin to Arduino

2. connect the output pins of IR sensors to Arduino's pin no 2 and 3

3. connect the pin no 4 and 5 of Arduino to L293D's input pins as shown in circuit.

4. connect the motor as shown in circuit.

5. connect all the connection as shown in circuit.

6. also connect the buzzer to both motors pins.

Step 4: #program and Code

here code is shown
just copy and paste it

int sensor1=2;
int sensor2=3;
int motor1=4;
int motor2=5;

void setup(){
pinMode(sensor1,INPUT);
pinMode(sensor2,INPUT);
pinMode(motor1,OUTPUT);
pinMode(motor2,OUTPUT);
}

void loop(){
C:
if(sensor1==LOW){
digitalWrite(motor1,HIGH);
digitalWrite(motor2,LOW);
delay(500);
digitalWrite(motor1,HIGH);
digitalWrite(motor2,HIGH);
A:
if(sensor2==LOW){
digitalWrite(motor1,LOW);
digitalWrite(motor2,HIGH);
delay(500);
digitalWrite(motor1,HIGH);
digitalWrite(motor2,HIGH);
delay(1000);
goto C;
}goto A;
if(sensor2==LOW){
digitalWrite(motor1,HIGH);
digitalWrite(motor2,LOW);
delay(500);
digitalWrite(motor1,HIGH);
digitalWrite(motor2,HIGH);
B:
if(sensor1==LOW){
digitalWrite(motor1,LOW);
digitalWrite(motor2,HIGH);
delay(500);
digitalWrite(motor1,HIGH);
digitalWrite(motor2,HIGH);
delay(1000);
goto C;
}
goto B;
}
}
}

here 500ms delay is used because gate is closed in this time. you can change this according to practical response

after dumping the code and connecting its not working how can i over come it can u provide exact circuit diagram instead of that please....have to submit my project

[monusuthar2016]

Hello rahul
I will add another circuit diagram tomarrow

[Rahul_972]

yeah thank you hope u add quickly so that i can complete my project

[Ankit-35]

Please give me the correct circuit diagram.

[madhavich]

Please give me a proper circuit diagram

[Rahul_972]

what happend provide me the circuit diagram

[Ankit-35]

Please sir give me the proper circuit diagram and program code, this is note working quickly

[Ankit-35]

Please sir give me the proper circuit diagram and program code, this is not working please.

[AmitP160]

Hi Sir.. Can you pls send the circuit diagram for the same ?

[Surisurendra]

Hii
Send me proper code and circuit diagram
This not working the wast project

[AkashS_7]

How do i remove the led and and connect it across the photo transistor? Can anybody send a proper circuit diagram for this

[Hla Win Aung]

Broher, I had seen your program is used motor 1 and motor 2. But , in the ckt is used one motor. Why, explain me please.

[ChandrakantI]

Plz send the proper circuit diagram

[ChandrakantI]

Hello the connections are not looking properly plz send the clear Vedio or picture

[dgoel26]

hi

could you please provide a better circuit diagram.

it is very difficult to complete the circuit with this diagram

[IramN]

Plz send me the circuit diagram of this project in my inbox.

[IdongesitW]

Big brother, I am very interested in this project. I need it for my training but we dont have the material in my country. Please how can you send a complete kit to me? Please reply to my inbox. Thank you.

[ŁøhîťhB]

Where is the material available?

[RaviP125]

Go to SP road , u will get all components in cheap prices

[KesanaH]

how did u connected a buzzer and didnt mention in the code
