    Every computer system works by taking input from the user, processing it and then
                     giving an output. The Micro:bit also follows this rule, it has both input and output

                     components that allow it to interact with the environment and users.

                     INPUT AND OUTPUT COMPONENTS

                     The Micro:bit has several built-in input and output components that help it sense

                     and respond to the world around it. The input devices includes buttons and sensors
                     for light, temperature, motion (accelerometer) and direction (compass). The output
                     devices include the LED display, which shows messages and icons and the sound

                     output, which produces tones.

                     The Micro:bit also has the ability to control external devices such as buzzers, LEDs,
                     motors and sensors via its Edge Connector pins and can use radio signals for wireless

                     communication to interact with other devices.

                     Some of the input and output devices are as follows:

                                    Light Sensor     Touch Sensor       Radio      Temperature Sensor

                                                                                                          Microphone
                      LED Display
                                                                                                          Sound Output

                                                                 Compass &                Edge Connector
                                Buttons (A and B)              Accelerometer

                        n  Buttons (A and B): The Micro:bit has two programmable input buttons, A and
                        B. These large buttons on the front can be programmed to perform different

                        actions when pressed, allowing the Micro:bit to respond to user inputs, such as
                        displaying a heart on the LED display.

                        n Microphone: It has a built-in microphone sensor. It allows the device to detect
                        sounds from the environment and respond to them, such as clapping your hands

                        to make the Micro:bit display a heart.

                        n  Accelerometer: An accelerometer is a motion sensor in the Micro:bit that detects
                        movement and tilt in different directions. It can sense actions like shaking or

                        freefall.

                                                                              Micro:Bit and the World Around Us
