    Observations

                      In the “Voice Control System” activity, students will observe how their Micro:bit responds to voice
                      commands. When they speak specific words or phrases, the Micro:bit will process the audio input
                      and perform corresponding actions, such as turning on an LED, activating a motor, or displaying
                      messages.

                      Students  can experiment with  different  voice commands  to  see  how  accurately  the  Micro:bit
                      recognizes them. They may also discuss the challenges of voice recognition technology, such as
                      background noise or variations in pronunciation.

                      Applications

                      Students, speaking LEDs can be embedded in children’s storybooks. When a child touches a picture
                      or a word, the LED lights up and narrates the story, making reading more engaging and interactive.

                          2.   What is the maximum voltage input allowed on the micro:bit’s external power supply connector?

                              (i)   3.3V                                       (ii)   5V

                             (iii)   6V                                        (iv)   9V
                          3.   Which language is NOT commonly used to program the micro:bit?

                              (i)   Python                                     (ii)   JavaScript

                             (iii)   Scratch                                   (iv)   C#
                          4.   What is the primary function of a micro:bit in a voice-controlled robot?

                              (i)   To play music                              (ii)   To process voice commands

                             (iii)   To display images                         (iv)   None of these
                          5.   How can a robot respond to a specific hand gesture?

                              (i)   By ignoring the micro:bit

                              (ii)   By using sensors to detect the gesture

                             (iii)   By playing a sound

                             (iv)   All of the above
