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
Build a classroom space and fix the switch sensor and motor with fan installed on it.
Use SMART Code to program and control devices.
Firstly, create the main program entrance. The example code is as follows:
Then, complete the switch sensor logic. When the switch is pressed and not pressed, there are two states. The example code is as follows:
Then, when the switch is turned on, programming is implemented to rotate the motor and switch the sensor. Every time the sensor is pressed, the motor rotates for 1 minute. The example code is as follows:
Finally, complete the programming of the ventilator. The example code is as follows:
Optimization and improvement plan.
Interesting thinking: Can the switch be kept normally open to achieve intelligent control based on environmental changes.
