When you come home, you turn on a light. Here, Circuit playground serves as a light sensing sentinel, noticing you turned on a light and, through the PowerSwitchTail II relay, turning on other lights and devices for you. Just tune the light sensitivity for the light you always turn on compared to the ambient level, and put CircuitPlayground somewhere out of the way but still able to detect the change.
NOTE: Don't have CircuitPlayground receive light from the same device(s) it turned on, or it will be
stuck in a self-feedback loop.
Also: The response time is necessarily slow to avoid rapid oscillations sent to the PowerSwitch II,
which could conceivably damage some downstream AC devices. Set this with the Slide Switch (+) or (-)
