This flowchart starts by taking two inputs: the current room temperature and the desired temperature set by the user.

It then compares if the current temperature is less than the desired temperature.

If yes, the heating is turned ON to warm the room.

If no, the heating is turned OFF because the room is warm enough.

The flowchart ends after deciding the heating state.

Variations - 2 Challenges

[intermediate] Draw a flowchart for a smart light that turns ON if it is dark outside and someone is in the room, otherwise it stays OFF.

[advanced] Draw a flowchart for a smart security camera that starts recording if motion is detected or if it is night time, and stops recording otherwise.
