    Applications

                      Home Appliances: Blinking LEDs are used in devices like washing machines,
                      microwaves, and air conditioners to indicate power, cycle completion, or
                      malfunction alerts.

                                                     Security Systems: In alarm systems, blinking LEDs are used to signal
                                                     when the system is active, armed, or when there’s an intrusion or fire
                                                     detected.

                      Programming the Automatic Fan

                      An IR sensor is a special sensor that can sense when something is nearby by detecting
                      invisible infrared light which is not visible to our eyes.

                      How Does It Work?

                      Infrared Light: Everything that is warm gives off some infrared light. This includes
                      people, animals, and hot objects. The hotter something is, the more infrared light it produces.

                      Detection: An IR sensor has a special part called a photodetector that can “see” this infrared light.
                      When infrared rays hit the sensor, it creates an electrical signal.

                      Responding to Changes: When something warm, like a person, moves in front of the sensor, the
                      amount of infrared light changes. The sensor can notice this change and do things like turn on a light
                      or set off an alarm.

                      Motor is a small device that helps machines or things to spin,
                      turn, or move.
