GPS /GSM Tracker


DESC:

With this program, Arduino waits for a phone call and send a SMS with the GPS coordinates.

Disclaimer: This is my first working version, testing was ok, but i don`t make responsible of unwanted SMS sends, use for security always  a pre-paid mode sim card. Use the code under your own responsability.

I think this is what he is saying !

With this program, Arduino waits for a phone call and then sends an SMS with the GPS coordinates.


Disclaimer: This is my first working version, testing was ok, but i don`t take responsibility for unwanted SMS sending,  for security always use  a pre-paid  sim card. Use of the code is your own responsibility.



Now Sir I like this bit of work and am wanting to build it .
What parts do I need ,where can I get them and will you please post the scematics and perhaps a construction diagram with notes .

I will not hold you responsible whatever even if it SMS's our political leaders . I would like to know where some of them are at times.
Governments should do what they were designed to do only.
Manage the larger issues best done by Government.

hey, i have 2 ideas


(1) checking the number before sending sms


(2) sending the data per gprs to a http-server. for example http://myserver.com/gprsinput.php?long='...'&lat='...'

Trenator, could you please write the parts you used to build this project?

trenator

hi, sorry for the delay.

Parts are:

Arduino

A LM7805 attached on a board for regulate voltage to 5v. and dont overload arduino

A ttl - serial converter , because my modem speaks on rs232 and arduino in ttl levels.

Modem GSM

and GPS module

Must read this stuff.....

it might be useful...

I'm sure this project could be "spiced up" a bit.

Does anyone know how to "read an incoming" phone number, on an Arduino? If so, please show us, cause then one one pre-program it to only send back GPS co-ordinates to a list of numbers, and not every number that phones in.
