Realization of automatic testing system, designed a light intensity under the condition of three different light intensity on the outside step instructions (weak, appropriate, strong), the specific requirements for:
(1) according to the topic selected light intensity type photoelectric sensor used in the automatic detection;
(2) according to the different light intensity of strong (weak), control motor and reversing.
(3) the machine circuit diagram system is given;
(4) simulation debugging scheme;
(5) the last on the experiment platform programming implementation,
