💪 Working Principle

The ATmega2560 continuously reads input signals from the ultrasonic sensor, LDR, and SOS button.

• When the LDR detects darkness (low voltage output), the LED automatically turns ON.
• When the SOS button is pressed, the buzzer activates to alert nearby people.
• The LCD displays the real-time status of the LED and buzzer.
• This integration of sensors and output peripherals provides an intelligent, responsive, and power-efficient assistive solution.
