4.Project Practice Process
1.Project Steps
2.According to the item list, fix the sound intensity sensor and RGB light.
Use SMART Code programming software to complete programming design.
Use SMART Code software for programming.
Firstly, complete the main program logic. The example code is as follows:
Then, create a variable to obtain the sound intensity sensor value. The example code is as follows:
Then, check the normal ambient sound decibel value on the main controller, obtain the threshold for sound control, and control the RGB lights to turn on and off. The example code is as follows:
Finally, complete the entire code. The example code is as follows:
