CAR TRACKER (GSM + GPS)

  In this project a phone set required having built-in GPS module where you can get location coordinates and GSM location through sms from your vehicle,There will be call originated from car while someone try to open car door.  You can get alert  from car while someone try to open car door   For call originating from car will required speed dial option in mobile phone set.  First enable speed dial option, save your number with specific digit ,  solder the desire button,   now   both wires from the will be interface with car doors switch, It means that if someone open the door switch will be operated resulting to dial the specific  speed dial  number.  Basic concept in circuit is that despite of different cellular mobile phone number in the tracking car should pass a combination (sequence) lock key, for this a simple 4081 AND gate IC were used where 4 keys required in a desire sequence, these 4 inputs were taken from 4028 (4 bit binary to decimal converter) IC to 4081, which is directly connected to 8870 DTMF IC outputs, in the last a simple touch on/off circuit were used from IC 4013.Interface between ICs 4028 & 4081 were done with the opt coupler PC817, Once sequence completed in IC4081, reset will required it is then done while using relay 2 along PC817.
