    Laser Sensor Timer

    My project starts from left to right but the same concept as yours. However mine will start from in between the break beams. Mine will start left on a pendulum type swing crossing the beam starting the timer. Then come back through that same beam, heading towards and crossing the second beam stopping the timer. MY QUESTION, will crossing over the first beam the second time stop the timer or will the timer keep counting til i reach the second beam. If so how would i fix this. Thank you.
