    SMART ECO ALARM SYSTEM

                                                                      Design a Smart Eco Alarm System using the
                                                                      micro:bit that senses light and temperature
                                                                      to help save energy. The alarm will flash LEDs

                                                                      or play a sound when the room is too hot or

                              CAPSTONE PROJECT                        too  bright,  encouraging  eco-friendly  actions
                                                                      like turning off lights or fans.

                     Session 1: Understanding Sensors and Planning

                     Activities:

                     1.  Learn about Input and Output Devices
                           Task: Research how the micro:bit uses light and temperature sensors as inputs and

                         the LED display or buzzer as outputs. Identify real-life uses such as alarms, weather
                         monitors or automatic lights and create a report.

                         Skills Practiced:  Understanding  sensor-based  input/output  and  environmental
                         awareness.
                     2.  Design Your Idea on Paper

                         Task: Draw a simple layout of the Smart Eco Alarm System showing the micro:bit,
                         sensor areas and outputs. Label input and output connections such as Pin 0, GND
                         and 3V.

                         Skills Practiced: Circuit representation and logical design planning.
                     Outcome for Session 1

                     A hand-drawn plan illustrating how the Smart Eco Alarm System works.

                     Session 2: Coding the Smart Eco Alarm in MakeCode
                     Activities:

                     1.  Create the Light and Temperature Alarm Code
                           Task: Open Microsoft MakeCode and create a new project named Smart Eco Alarm.
                         Use the light and temperature sensor blocks to detect changes in brightness and heat.
                         When light > 150, display a sun icon; when temperature > 30 °C, display a fire icon;

                         when both are high, play a short melody.
                         Skills Practiced: Conditional programming, sensor input handling and output control
                         using LEDs and sound.

                                                                                                                        65
