4.Project Practice Process
(Summary of Knowledge Points: 1. Components. 2. Program Modules. 3. Program Design)
1.Project video (in video format)
2.Project Steps
1.Fix the switch sensor, steering gear and RGB light according to the list of items.
2.Use the steering gear to build the opening and closing door.
3.Use smart code programming software to complete the programming design.
First, complete the switch logic setting. The example code is as follows:
Then, adjust the steering gear rotation angle to determine the steering gear angle when opening and closing the door. The sample code is as follows:
Then, in combination with RGB lights, the green light is on when opening the door and the red light is on when closing the door. The example code is as follows:
Then, combined with RGB lights and actuator control statements, test the status of door opening and closing. The example code is as follows:
Finally, complete all the codes. The example code is as follows:
4.Run the program, debug the switch and use..
