                                UNDERSTANDING BLUETOOTH TECHNOLOGY

                      Bluetooth is a wireless technology standard used for exchange data between devices over short
                      distances, using short-wavelength UHF radio waves. It is widely used in various applications, such
                      as hands-free headsets, fitness trackers, smart home devices and wireless speakers.

                      INBUILT BLUETOOTH IN MICRO:BIT

                      The  Micro:bit has an  inbuilt  Bluetooth  Low Energy  (BLE) feature  that  allows it  to  wirelessly
                      communicate  with  other  Bluetooth-enabled  devices,  such  as  smartphones,  tablets  and  other
                      Micro:bits.  This feature  makes  it  an ideal  tool  for  creating  interactive  projects,  like remote-
                      controlled robots, communication systems and data-sharing applications.

                      HOW IT WORKS:

                      The Bluetooth functionality on the Micro:bit works as follows:
                         ∑  Bluetooth pairing: To use Bluetooth on the Micro:bit, you first need to pair it with another
                          Bluetooth-enabled device (e.g., a smartphone app or another Micro:bit).

                         ∑  Sending data: Once paired, the Micro:bit can send data, such as sensor readings or receive
                          control signals from another device.

                         ∑  Micro:bit app: You can create custom apps on your phone or tablet to interact with the
                          Micro:bit via Bluetooth, such as controlling motors, sensors or even sending messages.

                                WHAT IS A SERVO MOTOR AND ITS TYPES?

                      A servo motor is a specialised motor used for precise control of angular position, velocity and
                      acceleration.  It is  widely used  in robotics,  automation and many  other  applications  requiring
                      accurate positioning and movement.
