    display. If “direction” is equal to 2, then the arrow points east. Otherwise,
                        the arrow points west.

                        To make the battery last longer, the program pauses for half a second after

                        the arrow appears then clears the screen.

                     Concepts

                     1.  Direction Detection using Accelerometer

                         Students  will  learn  how  the  micro:bit’s  accelerometer  detects  tilts  and
                        movements in different directions. They will understand how devices sense

                        motion and use this information to trigger an output.

                     2.  Conditional Logic in Programming
                         Students  will  explore  how  to  use  “if-else”  logic  to  create  conditions  for

                        displaying specific arrow directions. For example, if the micro:bit is tilted to
                        the right, a right-facing arrow will blink, reinforcing their understanding of

                        logic-based decisions in programming.
                     3.  Visual Output on LED Grid

                         Students  will  learn  how  to  control  the  LED display  by  programming  the
                        micro:bit  to  show  different  arrow  symbols  that  represent  the  direction
                        detected by the accelerometer. This concept connects to visual representation

                        in programming.

                     Observations

                     In the Direction Blinking Arrow using Micro:bit activity, students will observe
                     how the micro:bit responds to tilting in various directions. When the micro:bit is
                     tilted to the right, a blinking right arrow appears, and when tilted to the left, a

                     left arrow blinks. This gives them hands-on experience with how sensors detect
                     movement and how these movements are converted into programmed actions.

                     students  will  observe  how  quickly  and  accurately  the  micro:bit  responds  to
                     changes in direction and how the LED display adapts.

                     Application

                     Fitness Trackers:  These  devices  use accelerometers  to

                     track movements, such as steps, running, or other physical
                     activities, helping users monitor their health.
