18. We have to improve the STOP procedure to wait until you take off your
hand.
Change the STOP procedure to the following:
19. Save the program under the name CART7.
20. Put the SENSE near the black line.
21. Run and check the SENSE movement.
22. Put your hand in front of the SENSE, while it moves.
Change the values of the memories until the SENSE works well.
