Today car theft is a huge criterion for car owners. Although the manufacturers provide the car security system, but car thieves easily break those systems. Therefore, we plan to prevent the car from thieves using FUZZY LOGIC.
The car could be started only when the given password is correct. Use a 4x4 matrix keyboard to power the password. The LCD screen is used to show purpose. The microcontroller is the heart of the project, which controls the entire system.
The microcontroller is interconnected with the keyboard, LCD EEPROM, gas tank and battery control circuits. The password is stored in the EEPROM. The EEPROM is used because the stored password can be erased electrically and could store another password if necessary. When starting the vehicle, the password must be entered. If the entered password matches the stored password, the fuel tank opens and the battery control circuit is activated. The microcontroller is programmed to perform all these operations. But if the password entered does not match, then the microcontroller will not allow the gas flow and will not turn on the battery circuitry. Therefore, our circuit provides a guaranteed safety to the car or vehicle using this system.
