Car Security Using A-B-C Analysis

ATMEGA 2560 based car security system differs from other car security system in comparison of peripherals and overall security. The idea behind the project is to improve car security. In the project ATMEGA 2560 controller is being used, we placed three proximity switches below the accelerator, the brake and the clutch. A sequence is generated according to the pedals pressed by user. For example, if we assign ‘A’ to accelerator and ‘B’ to break &’C’ to clutch, the user can enter a number of sequences, like ACBA, AACB, BACB, etc. This sequence is transmitted to the microcontroller, which compares the entered sequence with the pre-stored sequence. If sequence matched microcontroller will allow ignition. If the sequence entered is wrong for more than three times, System uses a GSM module to send SMS to the owner of the car and a GPS to broadcast the location of the car. As well as buzzer will on and doors will be locked. The applications of this project can be extended to safes as well. System is also providing facility of changing password through mobile & facility of sending message to multiple mobile numbers. There is no need to carry extra accessories for this security system & this system is user friendly as entering password through accelerator break and clutch is quite simpler.
