This is great project indeed, very helpful, more strength to ur ideas. I suggest if you can add Google Map address and location, this project can be used as car tracker which can make it more useful for ur fans, especially me.

I think it required gps module to integrate with this project. nice idea, I will try it.

@@AhmadLogs yes it requires GPS module through which will get the geo location and you will now encode it in google like and send as message to the user.

@@ezeoluchukwu5104 It will possible. but the arduino program memory is limited. my code used 55% of memory. If it use gps, then the code becomes more bigger, and then, it required more memory. I am afraid if the arduino uno can handle it. but I will try

Dear, I have a question that, there is no Phone number used in your program so how can serial monitor show your phone number's ? please give me a proper solution for this issue.

[@AhmadLogs]

the phone numbers are stored in the eeprom. and we will store the phone numbers by sending sms. for example if you send "R" (without double quotation marks) from your mobile phone. and the phone number will be registered and stored at location 1. the same way you can register more phone numbers. to register phone number 2, you will send r2=[phone] (enter your own phone here) from your phone. and it will store on location 2. you must need to watch this kzbin.info/www/bejne/hXvGeIxqrrimatE
