4. I. Introduction of subject

5. Wonderful sensor
Voice-activated sensor 1 1
Color sensor

6. What is a sensor 2
The sensor is a detection device, can sense the measured information, and can, according to a certain law, convert the sensed information into electric signal or information output in other forms.
The way by which we access the outside information
The way by which mechanical equipment accesses the outside information
Light sensor
Humidity sensor
Gas sensor
Sound sensor
Taste sensor
Temperature sensor
Pressure sensor
Vision
Smell
Hearing
Taste
Touch

7. II. About light sensor

8. Light sensor 1 1
Light sensor

9. 2 About light sensor GND 5V
Include a sensitive resistor which can sense the light and shade change
GND 5V
Signal, which outputs the signal to the pin of the processor

10. 1 3 Connection of light sensor 你知道光敏传感器与机械臂怎么连接吗？
GND and 5V correspond to GND and 5V pins respectively
SIG is connected to EIO7 pin

11. 4 Reading of the light sensor value Step 2: print the light data
Operation log 4
Step 3: output continuously
Step 1: set the type of the interface EIO7
Step 2: print the light data

12. Exercise 1 5
Write a program to obtain the value of the light sensor, and through the light control, find out the maximum value and the minimum value of the light sensing data received.

13. III. Skills competition

14. It is time to operate by yourself!

15. I control my manipulator
Operation purpose: further exercise of the manipulator and light sensor
Operation task: write a program to achieve the sensitive intelligent light

16. Program example
Note:
LED light is connected to EIO5, and the light sensor is connected to EIO7

17. IV. Classroom summary

18. Summary What have we learned in this lesson?
-Connection and operation method of the light sensor
-Reading of light data of light sensor
-Write a program to achieve the application of switching on LED light automatically when the light is lower than a certain value
-Review basic knowledge about electronics and function and operation method of the manipulator interface

19. After-class thinking
In addition to the light sensor, are there other ways available to achieve the switching on/off of the light automatically? How to achieve?
