| **The ATmega328P Microcontroller** processes the information received from both sensors and executes the decision-making logic implemented in software. If suspicious activity is detected, such as movement during low-light conditions, the microcontroller activates the alarm subsystem. | **The ATmega328P Microcontroller** processes the information received from both sensors and executes the decision-making logic implemented in software.

| - | **The Buzzer Module** is used for generating sound alerts and is controlled through PWM signals generated by the microcontroller. At the same time, the **LED Indicators** provide visual feedback regarding the current state of the system, such as standby mode, alarm activation or Bluetooth connection status. | + | **The Buzzer Module** is used for generating sound alerts and is controlled through PWM signals generated by the microcontroller.

| **The Bluetooth Module (HC-05)** enables wireless communication between the embedded system and a smartphone. Through UART communication, the user can monitor alerts, retrieve event logs using commands such as GETLOG and interact remotely with the system. | **The Bluetooth Module (HC-05)** enables wireless communication between the embedded system and a smartphone.
