## Motion Light
Our next example is to turn on a light when motion is detected and it is dark, and turn it off after a period of time. This time, the `initialize()` function registers a callback on a state change (of the motion sensor) rather than a specific time. We tell AppDaemon that we are only interested in state changes where the motion detector comes on by adding an additional parameter to the callback registration - `new = "on"`. When the motion is detected, the callack function `motion()` is called, and we check whether or not the sun has set using a built-in convenience function: `sun_down()`. Next, we turn the light on with `turn_on()`, then set a timer using `run_in()` to turn the light off after 60 seconds, which is another call to the scheduler to execute in a set time from now, which results in `AppDaemon` calling `light_off()` 60 seconds later using the `turn_off()` call to actually turn the light off. This is still pretty simple in code terms:
