                     Troubleshoot:
                         No Sound:
                         ◦     Verify that the code is uploaded correctly to the Micro:bit.

                         ◦     Check for loose wires or incomplete circuits.

                         ◦     Ensure the speaker or piezo buzzer (if used) is connected properly.

                         Incorrect Tones:
                         ◦     Review the code blocks to ensure each button or gesture corresponds to the correct note.

                         ◦     Make sure all inputs are assigned properly in MakeCode.

                         Micro:bit Not Responding:
                         ◦     Reset the Micro:bit by disconnecting and reconnecting the battery pack.

                         ◦     Re-upload the code in case of programming errors.

                         Gesture Not Recognized:
                         ◦     Increase the sensitivity in the code by adjusting the thresholds for tilt or shake detection.

                                                                                              Exploring Microcontrollers  141
