Drowsiness Alerting Device

Hi friends

As you know drowsiness is a major problem when we drive any vehicle.

Most of the accedent occurs due to this especially in india.

Thats why we have made this project for alerting the driver from the drowsiness and prevent it to accedent.

In this device we have use an attiny85 microcontroller because it is very small in size as compare to arduino nano or other arduino boards.

I have set the delay time to 2 seconds but you can change it according to your choice in the program.

For this project we need following component

HARDWARE -

1.) Attiny85 microcontroller

2.) Buzzer

3.) LED

4.) IR sensor ( eye blink sensor )

5.) capacitors 0.33uF and 0.1uF

6.) 7805 Voltage regulator IC

7.) Battery

8.) Switch

9.) Zero PCB

10.) Few wires

TOOLS -

1.) Soldering iron

2.) Solder material

SOFTWARE -

Arduino IDE

1.) For attiny85 IC board manager setup and bootloading the IC you can watch the steps on my video

Or you can also follow the steps from this link

https://create.arduino.cc/projecthub/arjun/program...

2.) Now make the connection according to this circuit diagram

3.) Before uploading the code you have to upload Arduino ISP example code in your Arduino board.

4.) From tools Select attiny85 from the board then select clock speed to 8Mhz and then select programmer as ISP.

5.) Now upload the main program to the attiny85 IC through the Arduino board.

IN THIS PROJECT WE ARE USING ATTINY85 IC INSTEAD OF ARDUINO MICROCONTROLLER . THIS DEVICE CONSIST OF ATTINY85 IC, EYEBLINK SENSOR ,BUZZER,LED WE ARE USING 3GPIO PINS OF ATTINY85 FOR ANY ISSUE CONTACT - www.crazytronics2000@gmail.com */

if (digitalRead(sensor) == LOW) // Again check whether the eye is close at this instance { analogWrite(buzzer,sound_sets[index+1]); // Buzzer will generate 2nd sound having analog value 200 delay(interval); // This sound will generate for 100 milliseconds continue; // If eye is remains closed at this instance then this while loop will be start again from the top. } } } } }
