12. Case 11: Smart Lamps for Basketball Courts¶
In the city, there are places for citizens to exercise, such as basketball courts. Whenever it is night, the basketball court will always turn on the lights, thus, we can make a smart lighting that will automatically turn on the lights when it detects that someone is moving on the basketball court, otherwise it will automatically turn off the lights.
Light on the lamps if there are people on the basketball courts and turn off the lamps if there is no one there.

Judge the sound level, if the value is over the threshold, program to light on the LED; or program to turn off it.
If the sound level is over the threshold, it means there are people on the courts, program to light on the leds; or program to turn off the lights.
