Case 11: Smart Lamps for Basketball Courts

Introduction​

  • 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.

Function​

  • Light on the lamps if there are people on the basketball courts and turn off the lamps if there is no one there.

Notice: If you met a tip indicating that some codebases would be deleted due to incompatibility, you may continue as the tips say or create a new project in the menu.
