/*
  - If either sensor is triggered for at least 3 seconds
    - the motor starts moving in direction 1 (for a set duration of time).
      - During movement in direction 1, the sensors do not monitor
      - Once the initial movement is complete, sensors monitor activity within 1.5 feet.
    The motor will not move in direction 2 (opposite dir.) for the same set amount of time until the path is clear for at least 3 seconds.
    While the motor is moving in direction 2:
    Continuously monitor the sensors.
    If the sensors detect an object within 1.5 feet, stop the motor and reverse direction back to direction 1.
    Move in direction 1 for the same amount of time it was moving in direction 2
    Once the movement back to direction 1 is complete, monitor the sensors again.
    If no activity is detected for at least 3 seconds, the motor will attempt to move in direction 2 again.
