Joseph,
How does it work then?
I thought the idea was that there is a randomly emitted light emitted, not a constant light nor a light on a constant schedule. When you the switch, the eventual emitted light can be detected by the sensor and that is what either turns on or off the light.
Now that the switch is up, what is going to change that status? Doesn’t the light source continue to emit light sporadically? And the when you move the switch to the other position, how does that let the sensor know to change the status, presumably, as far as the sensor should know the fact that no light has hit it can either be a function of the sensor being blocked or just that the it has randomly not emitted.
Although I guess the sensor can be tied to the emitter that it is aware when the random emission is made and if it does not detect an emission that is made, the switch will then again change for on to off or vice versa.
That would seem to defeat the randomness to me.
