Circuit Operation: PIC16F877 used in the circuit of the B and D as input port is selected. 8 of these units with port B doors, windows and etc.. from places logic 1 or 0 state is evaluated. D port is necessary for system operation or stopping the input of a predetermined password has been supplied. A and C are chosen as output port with port status LEDs and alarm circuit has been. C port to the B port is where you get the warning from the 7 segment LED display is used as the indicator showing. Instead of port 1 LED alarm circuit 1 or 0 is used to determine whether, enter the password warning LED LED 2, 3 the password is correct, and that LED LED LED yandıkd 4 seconds after the system is activated. 4 LED lights up when the system stops enter the password.
