    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.
