    A sensor is a special electronic part that can detect changes such as movement,
                      light, sound, direction or temperature. It collects information and sends it to the

                      robot’s brain or microcontroller, which decides what to do next.
                      Robots cannot see or hear like humans do, but they use sensors to understand the

                      world around them. Sensors can detect movement, direction, temperature, light
                      and more.

                                                                          Think about  your smartphone.  It turns
                                                                          the screen automatically when you tilt

                                                                          it or counts your steps when you walk.
                                                                          This happens because  of sensors. The

                                                                          Micro:bit also has built-in sensors that
                                                                          allow it to do similar things.

                      MOTION SENSOR

                      The Micro:bit can sense movement through its motion
                      sensor, also known as the accelerometer.

                      It detects when you shake, tilt or turn the board in
                      different directions. which means it can detect changes

                      in speed and direction. When you move or shake the                 Motion
                      Micro:bit, the accelerometer reacts to those changes.              Sensor

                      For example,  when you  shake  the  Micro:bit,  the  accelerometer  detects  the
                      sudden change in the board's position. It quickly measures how much the Micro:bit

                      has moved.

                      Similarly, if you tilt the Micro:bit (left, right, up or down), the accelerometer can tell
                      in which direction you’ve moved the device.

                      It measures the angle of tilt  and sends this information  to  the Micro:bit’s  brain
                      (the microcontroller), which can then trigger an action.

                      These movement  signals  are sent as data to  the Micro:bit,  which  can then use

                      the data to perform different tasks. For example, shaking the board might make
                      the Micro:bit show a smiley face or tilting it left could make an arrow appear on

                      the screen pointing left.
                      You  can use  these  signals  to  create  interactive  projects,  such  as  games  where

                      shaking the Micro:bit triggers an event, like rolling a dice or jumping over an obstacle.
                      You can also create timers where tilting the Micro:bit counts down the seconds.
