Set a complex pattern to play back on your flashlight. This pattern is in the same format as the Android Vibration pattern
You can easily create a pattern by using the built-in helper or you can do it manually.
The first value indicates the number of milliseconds to wait before turning the flashlight on.
The next value indicates the number of milliseconds for which to keep the flashlight on before turning it off.
Subsequent values alternate between durations in milliseconds to turn the flashlight off or to turn the flashlight on.
