Overview

This project utilizes an Arduino Nano and an IR sensor to detect closed eyes (indicating potential drowsiness). When the IR sensor detects closed eyes for 2 seconds or more, it stops the motorized car, activates a buzzer, and lights up a red LED as a warning until the eyes are opened again.

Features

• Eye Detection: Uses an IR sensor to detect closed eyes.
• Safety Alert: Stops the motorized car and activates a buzzer and red LED when eyes are closed for 2 seconds.
• Automatic Reset: Resets the system when eyes are opened again.

Components Used

• Arduino Nano: Microcontroller for sensor interfacing and motor control.
• IR Sensor: Detects eye movements (open/close).
• Motor Driver: Controls the movement direction of the car.
• LED and Buzzer: Indicators for alert notifications.
