Clap lights

What is the primary function of the sound sensor on the micro:bit?

• To measure temperature

• To detect light levels

• To detect sound levels

• To measure humidity

In a project using the micro:bit's sound sensor, which of the following scenarios would be a practical application?

• Turning on a light when it gets dark

• Activating a motor when a loud sound is detected

• Measuring the distance to an object

• Tracking temperature changes

Why do we set the loud sound threshold to 128?

• 
  So that the Microbit can detect any sound we make

  
  

• To activate the sound sensor

• So that the Microbit can detect a sound as loud as a clap
  

• So that the Microbit can detect a sound louder than a clap

Where do we find this block?

• LED category

• Music category

• In the Input category under the more... section

• Advanced section

Why do we use this code snippet?

• To check if the Lights are off

• To check if the Lights are on

• To check if the Lights are not on

• To toggle between lights on and lights off with each clap

What is the primary function of this code?

• To display an LED pattern continuously

• To react to a loud sound by toggling an LED pattern

• To change the sound threshold dynamically

• To display different patterns based on button presses

How does the code determine when to switch the state of lightson?

• By checking the time elapsed

• By checking the loudness of the sound

• By pressing a button

• By adjusting the sound threshold

What does the code do if lightson is true after detecting a loud sound?

• It shows a 5x5 LED pattern

• It clears the screen

• It turns off all LEDs

• It decreases the sound threshold

What happens when a loud sound is detected in the code?

• The screen clears

• The LED matrix turns off

• The value of lightson toggles (changes between true and false)

• The sound threshold increases

What is the initial value of the variable lightson at the start of the program?

• True

• False

• Undefined

• 128
