About this project

Now a day a lot of accidents occur due to the drunk driving and it need to stop people to drive after drunk. The alcohol car safety system provides a system that prevents such accidents in intoxicated position.

This system uses the sensors and use it to detect the driver is intoxicated or not if it detect such thing then it automatically set the warning alert to driver that he is not in the position to drive the and this system automatically turn off the ignition of car.

Step 1: Parts Used

  • Alcohol sensor
  • LED light (optional for indication)
  • Nokia 5110 LCD
  • Buzzer
  • Wires
  • Relay

Step 2: Make the Connections as Shown in Pic and Schematics

Connect the the Nokia LCD pin as follows:

  • SCK - Pin 8
  • MOSI - Pin 9 //
  • DC - Pin 10 //
  • RST - Pin 11 //
  • CS - Pin 12

And connect the sensor out pin in pin 7 of Arduino and connect the relay and buzzer pin to Arduino pin 13

Make the connections stated above and as described in schematics pic above.

Step 3: Now Upload the Code to Arduino

Now download the code from link below and upload it to Arduino. Your system is now ready!
