What is a variable in Micro:bit programming?

• A button you can press.

• A container for storing data.

• A sensor for detecting temperature.

• A built-in LED display.

Which of the following is a correct way to create a variable in MakeCode?

• Click "Add Sensor".

• Drag the "Create Variable" block.

• Use the "Math" category.

• Write a Python script only.

What does the compass in a Micro:bit measure?

• Distance traveled.

• Direction in degrees.

• Amount of light in a room.

• Time taken for an activity.

If the compass shows 90 degrees, which direction is the Micro:bit facing?

• North

• East

• South

• West

How can we display the compass direction?

• Press button A.

• Tilt the Micro:bit back and forth.

• Show number "compass heading"

• Nothing, it works automatically.

What does the radio feature on the Micro:bit allow it to do?

• Play music.

• Send messages to other Micro:bits wirelessly.

• Measure temperature.

• Turn on a light bulb.

Which block would you use to send a number over the radio in MakeCode?

• Show Number

• On Radio Received

• Radio Send Number

• Create Variable

If you set the radio group to "1" on one Micro:bit, what must you do on another Micro:bit to communicate with it?

• Set the radio group to "2".

• Set the radio group to "1".

• Use the compass to match directions.

• Shake both Micro:bits.

What is the purpose of using a variable with the radio feature?

• To display the time.

• To store and send data like scores or sensor values.

• To calibrate the compass.

• To connect to a Wi-Fi network.

How can you avoid message interference when using the radio feature on multiple Micro:bits?

• Use different radio groups for each pair of Micro:bits.

• Calibrate the compass before sending messages.

• Shake the Micro:bits before sending messages.

• Increase the brightness of the LED screen.
