/*

 * This is the Arduino code for an: 
 * Infrared Obstacle Sensor and displaying the time on 6 digital display and serial monitor.
 * Uses preprogrammed distance and converting it into mph.

***Still needs to count and store laps for average #of laps once button press
***Still needs to use 2 digit separate display the lap count for the above laps once button press


IR Sensor Wiring:
Brown: 5V DC
Blue:  GND
Black: Signal, to PIN 3

Arduino pins to the Large Digit Driver IN
