                  A. Tick ( ) the correct option.

                      1.  What is the main advantage of a servo motor compared to a regular motor?

                           (i)  It spins faster

                           (ii)  It moves to precise angles

                          (iii)  It consumes less power

                          (iv)  It works only with light sensors

                      2.  Which sensor can be combined with a servo motor to control movement based
                           on environmental light?

                           (i)  Pressure sensor                         (ii)  Light sensor

                          (iii)  Temperature sensor                     (iv)  Humidity sensor

                      3.  In a micro:bit program, which signal does the servo motor respond to?

                           (i)  Voltage level                           (ii)  Temperature data

                          (iii)  Angle instruction                      (iv)  Pressure data

                      4.  What happens when button A is pressed in the micro:bit program to control

                           a servo motor?

                           (i)  The motor spins continuously

                           (ii)  The motor moves to 45 degrees

                          (iii)  The motor moves to 180 degrees

                          (iv)  The motor does not move

                      5.  In an automated shading system, what does the servo motor do when the
                           light sensor detects too much light?

                           (i)  Opens the window                        (ii)  Closes the shades

                          (iii)  Turns off the light                    (iv)  Adjusts the temperature

                  B. Fill in the blanks.

                      1.   A servo motor can move and hold at specific                             .

                      2.  To control the servo motor in a micro:bit project, you can use the
                                              blocks from the block palette.
