How would you modify the sample code provided, or create your own code that includes the following features?

  • Adjust Sensitivity: Change the current thresholds in the if/else if statements. How does this change the sensitivity of your display?
  • Add Sound Feedback: Make the micro:bit play a different sound effect for each level of current (e.g., a low tone for low current, a high tone for high current).
  • Display Exact Current: Add a button (e.g., on button A pressed) that, when pressed, temporarily shows the exact numerical current reading on the micro:bit’s displays.
