GSM based car engine control Implementation to stop the car theft

An embedded system is a combination of software and hardware to perform a dedicated task.Some of the main devices used in embedded products are Microprocessors and Microcontrollers. Microprocessors are commonly referred to as general purpose processors as they simply accept the inputs, process it and give the output. In contrast, a microcontroller not only accepts the data as inputs but also manipulates it, interfaces the data with various devices, controls the data and thus finally gives the result.

As everyone in this competitive world prefers to make the things easy and simple to handle.In this project we deal with the security of the vehicle. when ever the GSM modem receives the message from the particular mobile then the car engine gets stopped .The mobile number from which the message is being sent should be the authorized mobile number. The authorized mobile number should be feeded into the system through the keypad and the number is stored in the EEPROM.
