Security lights include switches and motion sensors. System operation is toggled. The mechanism is disarmed while the switch is off. The switch turns off the light but arms the mechanism. The motion sensor activates the light when the system is armed. The light turns off after 10 seconds of inactivity. UML state diagram the "security light system" states.

Motion detectors and on/off switches are standard in security lighting. A switch activates the system. Turning off the switch deactivates the device. This switch will turn off the light but will also arm the device. If the system is on and the motion detector detects motion, the light will activate. After 10 seconds of inactivity, the light will automatically shut off.

Troubleshooting in Daily Life Troubleshooting is a technical term for solving a problem. Chances are you have already done some troubleshooting in your daily life. What are some examples of troubleshooting that you have experienced? What were you trying to fix and why? When you were doing it, did you think of it as "troubleshooting" or not? If you did the same activity today, would you think of it as "troubleshooting" now? Could you provide documentation for someone else who may have had the same issue so they could resolve it? How would you do that? What would you include?
