Final Project: SafePhone

There are, on average, more distracted driving accidents that occur that lead to death in the United States than any other type of accident occurrences. According to the Federal Communications Commission (FCC), nine people are killed and 1,000 are injured in distracted driving related accidents every day in the United States.

For my final project, I made a game that will encourage drivers to leave their phones in the cell phone holder while they drive. (Note: My original idea included an LCD Display but while working with it, it decided to stop working.)

 If the driver stays at least 21 cm away from the device, they will receive 1 point every 10 seconds but if they get within 19 cm of the phone, the program will deduct 10 points from their total point value.

The hall effect sensor detects if there is a magnet present and the Sharp IR sensor detects if the driver gets close to the cell phone.

The idea is for the driver to be able to claim social media credit with their friends and help them become aware of their role in safe driving.
