Instructables
Bring out your 3D glasses and enjoy viewing in a novel way! I have added a new dimension to my instructable. If you do not have 3D glasses, then you can make one yourself. The following link explains how to make 3D glasses ( link ).

Please Note: This instructable contains 3D images which are best viewed with Red and Cyan 3D Glasses. However, for those of you who do not have 3D glasses, this instructable also contains 2D images.




Every year about 700,000 vehicles get stolen in US. In fact, a car is stolen every 45 seconds.

We all love our cars and whether it is a roaring Lamborghini or a purring Prius, we are attached to it and wish that it never gets stolen.

I am very attached to my family car and take lots of precaution that I do not park my car in secluded places or double check that I always lock my car when I park it anywhere and always carry my car keys with me. However, I am still worried whether my car is safe. In order to get rid of these genuine worries, I decided to design my own low cost car tracking system.

In this instructable, I have explained the process of building one's very own Global Car Tracking System -'Athena' - for a cost of just 100$. The steps for building this device is very simple and explained in a lucid manner. The skills required for you to build this is minimum (Basic knowledge about electronics and the Arduino IDE).

I have christened this device by the name 'Athena' because Athena is the Greek Goddess of navigation. 

So what are we waiting for.....let's get started.......

i'm using new Arduino GSM Shield integrated antenna (telefonica/bluevia) to built this tracking device and encountered some problem. my tracking device is able to receive sms and get the coordinates. but it cannot reply the sms to the predefined number. the image is my current output.

and this is my coding program. Can someone help me figure out what seem to be the problem and how to solve it. Thanks

Also, is there a way to create a log with this that stores on the sd card so I can see my routes, distance, speed, heading etc.. The links below show logs on sd and phone tracking when stolen...

Hello, where can I buy the GPS and GSM ??
Thanks

DanB219 days ago

This is brilliant, well done you. Is it possible to convert the SMS message to Google maps format, so you simply click the link sent in the message to open Google maps automatically, this would be awesome.

This is a great idea for those of us with not much money and the less popular cars.

But for people that have the more desirable popular cars, if there care is stolen by a professional car ring, it might not help because with those thieves it is not long before your car will be in a shipping container destined for a south american country like Peru and although it is a great project there is no gps tracker that can transmit or receive through the steel walls of a steel shipping container.

Luckily, I have a less desirable older Lincoln and this great project is going on my list of projects to make.

Thanks!

Hey all ,

I am very disappointed. Nobody could help me. Someone asked me $ 15, I am not able to pay. I liked the project and wanted to test it. Maybe someone worked. To me it did not work. I used: Arduino Duemilanove (Mega) , Arduino shield GSM and GPS receiver 600L Cirocomm. All is ok because work well in other applications. The main problem is that not receive SMS with a password. In other tests can send and receive sms. The GPS receiver works very well in other applications. I think I'll give up this application. All the best to everyone.

Really nice work. I am in the process of building one of these for my Uncle (landscaping business, Jeep was stolen before = loss of income) Commercial examples are $2/300 + and some require subscription. All this for around €50 and a prepay SIM with some credit, too good!! Thank you for bringing this to my attention.

I've been trying to make a few slight modifications to your code, one is. Seen as most phones these days are smartphones, I want to include a google maps link so you can click direct from the text to your vehicles location.

The google maps URL system is pretty straightforward, just

https://maps.google.com/maps?q=46.352524+N+7.22842...

So I was hoping including this to the text message would generate a URL to point to the vehicles location. My code is like this;

[code]

Sim900Serial.println("AT CMGS = \"**********\"");//The predefined phone number

delay(100);

Sim900Serial.print("LAT: ");

Sim900Serial.println(LAT/1000000,7" N");

Sim900Serial.print("LON : ");

Sim900Serial.println(LON/1000000,7" W");//the content of the message

Sim900Serial.println("");

Sim900Serial.println"Google maps URL: https://maps.google.com/q="LAT/1000000,7"+N+"LON/1000000,7"+W");

delay(100);

Sim900Serial.println((char)26);//the ASCII code of the ctrl z is 26

[/code]

I was wondering if anybody could forsee any problems, I mean the google URL system is just http:/maps.google.com/q=LAT+N+LON+W, don't think too much could go wrong there, but you never know.

Also I would REALLY appreciate some help if somebody could tell me how to add the speed and heading into the text.

AND FINALLY, I would like to have 2 separate passwords/triggers, like sending "locate" would behave as the example in the 'ible and text the vehicles LAT, LONG, SPEED, HEADING and the URL once.

But texting "STOLEN" or "CONTINUOUS" would send the info every 5 mins (or other variable), until "STOP" is received, which would put the system back into standby state.

I know I have asked a lot of questions and it's a big ask, but these things come naturally to some! I would be REALLY grateful if someone could help me out, but I think some of these suggestions could be of use to others also and help make this amazing instructable even better!!

Dark_eye brenryan2 months ago

hi, did you manage to include google maps location to the message?

brenryan Dark_eye2 months ago
Hi, haven't got around to building it yet....

But from the tests I've done, if you output the lat&long in that format

(https://maps.google.com/q="LAT/1000000,7"+N+"LON/1000000,7"+W)

it will create a valid URL with a nice little arrow right on your location.

I changed the URL generation segment to;

[CODE]

SIM900.print("AT+CMGF=1\r"); // AT command to send SMS message
delay(100);
SIM900.println("AT + CMGS = \"+12345678\"") //The predefined phone number
delay(100);
Sim900Serial.println("SAT fix received;"); // The content of the message.
Sim900Serial.print("LAT: ");
Sim900Serial.print(LAT/1000000,7);
Sim900Serial.println("° N");
Sim900Serial.print("LON : ");
Sim900Serial.print(LON/1000000,7);
Sim900Serial.println("° W");
Sim900Serial.println("");
Sim900Serial.println("Google Maps URL:");
Sim900Serial.print("https://maps.google.com/q=");
Sim900Serial.print(LAT/1000000,7);
Sim900Serial.print("+N+");
Sim900Serial.print(LON/1000000,7);
Sim900Serial.println("+W");
delay(100);
Sim900Serial.println((char)26); //the ASCII code of the ctrl z is 26

[CODE]

Seems to work better.

Let me know how you get on or if you have any suggestions/tips, as I said it's been bumped down my list a bit, but will be building it at some point...

Good Luck!
Seaha brenryan2 months ago

hey guy can u send me your full sketch pls

brenryan Seaha2 months ago

Send you a PM so we're not spamming the page, good luck!

Jayvis Vineet Gonsalves (author)  brenryan2 months ago

The problem is that every time I upload the code to this webpage a few + operators are automatically removed out from the code, hence you'll might be experiencing an error when trying to use it in your project.

My computer in which I have saved the program is currently down, but I could pm you'll the code once my PC is up and running.

Thanks man that would be great if you can remember, thanks!

Dark_eye brenryan2 months ago

okay, nice. is the original code working for you, mine can get the reply sms?

brenryan Dark_eye2 months ago

Nope, can't get nothing working, not sure if there's a problem with my shield.

Can't get it to connect to the network without hitting the power button : /

I can't even get it to send SMS in the SMS test sketch.

Struggling with AT commands.

Did you just use the commands in the Instructable?

hgaston2 months ago

How are you guys powering the arduino in your car?

Seaha2 months ago

Hey Guy pls help me i have a Gsm Shield from Tinysine and it doesnt connect automatical i always have to press the power button.

Why????

Jayvis Vineet Gonsalves (author)  Seaha2 months ago

Check the data sheet of the GSM shield. It should have some info about software starting the shield.

Seaha Seaha2 months ago

And why i can not delet the

void SIM900power()

command from my scetch i every get the error message

GPS_Auto:50: error: expected unqualified-id before '{' token
