The project is based on a Gsm/Gps/Gprs. Its main function is to detect a illegal entry and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. I use the recent product by SIMCOM – SIM908 which operate on 5 – 12 volt dc supply, which makes it work on wide-range dc power supply… Well i still believe that i can burn a code of 21kb into program memory chip of 14kb (pic16f876a), but, it works all good…. hehehe…
maybe one of this days am gonna write a code of 30kb for this mircontroller chip, just wanna confirm the max. program memory size…. The featuring mircontroller chip is the pic16f876a, the reason i keep using this chip is because it cost less than $2 and I guess is available in all country…
Step 1: SIM908 SETUP
Step 2: CIRCUIT DIAGRAM AND PROTEUS SIMULATION
Step 3: MOTHER CONTROL PCB PRINT OUT
