    4.  Which of the following is an example of an input device on the Micro:bit?

                                    (i)  LED Display                         (ii)  Radio

                                   (iii)  Speaker                            (iv)  Button A

                        5.   Identify the pins that are commonly used for connecting external devices like LEDs
                            or buzzers.

                                    (i)  Pins 0, 1 and 2                     (ii)  3V Pin

                                   (iii)  GND Pin                            (iv)  Touch Sensor

                     B.  Write ‘T’ for true and ‘F’ for false.

                        1.   Micro:bit has both input and output components that allow it to interact

                            with the environment and users.

                        2.  An accelerometer is a motion sensor built inside the Micro:bit.

                        3.  The LED display has a 5×5 matrix of 25 red LEDs on its front.

                        4.   A buzzer is a small electronic device that produces sound.

                        5.  The gold Micro:bit logo can be used as a speaker.

                     C.  Fill in the blanks using the given hints:

                        1.   The Micro:bit  has gold  strips  along its  bottom  edge,  called               Hints
                                            .                                                              Bluetooth
                                                                                                              Pins
                        2.  Micro:bit has a built-in                  sensor.                                  25

                        3.  The LED display is an output device that emits                      .            3V pin
                                                                                                             Light
                        4.   There  are                  pins  on the edge  connector,  each
                            designed for different purposes.

                        5.   The                provides power to external devices and can also power the Micro:bit.

                     COMPETENCY-BASED QUESTIONS

                     1.  Arjun wants  to  build  a mini  weather station  using  the  Micro:bit  that  shows the
                        temperature and gives a warning when it gets too hot. Which input and output devices
                        should he use to make this project work?

                     2.  Aarav wants to display his name on the Micro:bit when he presses a button. Which
                        input device should he use to make this happen?

                                                                              Micro:Bit and the World Around Us
                                                                                                                        63
