                         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

                             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?
