(Summary of Knowledge Points: 1. Components. 2. Program Modules. 3. Program Design)
1.Project video (in video format)
2.Project Steps
1.Fix the light intensity sensor and RGB lamp according to the list of items.
2.The RGB lamp is designed and fixed with reference to the shape of the street lamp, and the light intensity sensor is placed on the top of the street lamp to ensure that the receiving light source is not blocked.
3.Use smart code programming software to complete the programming design.
First, create a program entry. The example code is as follows:
Then, the numerical display of the light intensity sensor is programmed to distinguish between day and night. The example code is as follows:
Then it combines the light intensity sensor and RGB lamp to realize the automatic switching of lights. The example code is as follows:
Finally, complete all the codes. The example code is as follows:
4.The rendering effect is similar to the real street lamp automatic switch scene in daily life.
5.Run the program, debug the switch and use.
