Driver Drowsiness Detection System

A real-time drowsiness detection system using Python, OpenCV, and an Arduino to trigger physical alerts. This project monitors a driver's eyes and activates a buzzer if signs of sleepiness are detected and makes the motor stop.

How It Works

1. Detection (Python): A Python(Opencv script) uses a webcam to capture video. It employs the MediaPipe library to detect facial landmarks and calculates the Eye Aspect Ratio (EAR) to determine if the eyes are closed.
2. Logic: If the eyes remain closed for more than 1.5 seconds, the system classifies the driver as "Asleep".
3. Alert (Arduino): The Python script sends a signal ('0' for asleep, '1' for awake) via serial communication to an Arduino. The Arduino then activates a buzze to alert the driver and makes the motor stop.

Setup and Usage

1. Hardware Setup: Assemble the circuit according to the Circuit diagram.jpg.
2. Arduino: Upload the Arduino_code_DDDS_.ino sketch to your Arduino Uno.
3. Python:
   • Install the required libraries: pip install opencv-python mediapipe pyserial numpy
   • In Main code(DDDS).py, make sure the ARDUINO_PORT is set to the correct COM port for your Arduino (e.g., 'COM4').
   • Run the script from your terminal: python "Main code(DDDS).py"
