Design a security system for a room. The system has two LEDs, one push button, a PI sensor$,$ and a buzzer. The system starts in IDLE state. LED$-1$ is ON and LED$-2$ is OFF. The system continuously monitors for motion. Once the motion is detected, the system transitions to recognition state. In this state the person is authenticated. LED$-1$ is off and LED$-2$ is off. If the person is authenticated, the system transitions to Open state. In this state the LED$-2$ is ON$.$ The system remains in this state for $10$ secs before returning to idle state. If the person is not authenticated, the system transitions to alarm state. The LED$-1$ and LED$-2$ are OFF and Buzzer is ON$.$ The system remains in this state until pushbutton is pressed to transition it back to idle state.
