CAN Based Security System

Description

CAN Based Security System is more and more microcontrollers are embedded in a large area of products from industrial to domestic domains. A good example is an automobile, a modern one containing tens of microcontrollers. As their number increased the communication between them became necessary.

In the kit CAN-based security system the serial solution was preferred and a lot of serial buses and protocols were developed optimizing different parameters of the communication. Several examples are: RS232, LIN, and SPI, CAN and so on. In this kit that is CAN-based security also we have tried to design the same communication protocol where there are three microcontrollers each having one specific task.

This CAN-based security system kit is the first control will be interfaced with the keypad to check the password. The second controller will be interface with the buzzer and the gate opening circuit. The third controller will be interfaced with the 16×2 LCD. If the password entered is correct there will be no alarm and the gate will be opened with proper display of encrypted password on the LCD and the notifications also
