/*

 * 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

 6 -> CLK (GREEN)
 5 -> LAT (BLUE)
 7 -> SER on the IN side (YELLOW)
 5V -> 5V (ORANGE)
 Power Arduino with 12V and connect to Vin -> 12V (RED)
 GND -> GND (PURPLE)
 8 -> Push Button
 START Input 

Arduino pin for LAP DISPLAY
