Micro:bit Timer Events and Functions

What is the primary function of an event-driven system like micro:bit?

• To only execute code when the device is powered on

• To execute all code at once regardless of events

• To wait for an event to occur and then execute the corresponding code

• To execute code continuously without waiting for events

Which of the following is an example of an event block in micro:bit?

• For loop

• If statement

• While loop

• On button pressed

Why is a timer event preferred over a pause block?

• It is more accurate

• It allows the program to run smoother without blocking

• It is easier to code

• It uses less memory

What is the main advantage of using Python for creating a timer event in micro:bit?

• Python allows for more complex event handling

• Python can create a timer event with just a few lines of code

• Python is the only language supported by micro:bit

• Python is faster than other languages

What is the purpose of the 'toggle' block in the blinking LED example?

• To turn the LED on and off alternately

• To increase the brightness of the LED

• To change the color of the LED

• To decrease the brightness of the LED

How often does the timer call the blinking function in the example?

• Every 1000 milliseconds

• Every 500 milliseconds

• Every 200 milliseconds

• Every 100 milliseconds

What should you replace 'pass' with in the default function when setting up the timer?

• The name of the function you want to call

• The micro:bit version

• The time interval in milliseconds

• The LED pin number

In the Python code, what does 'control.set_interval' do?

• Sets the time zone for the micro:bit

• Stops the program execution

• Defines the interval at which a function is called

• Pauses the program for a set time

What is the final step after creating the timer event in Python?

• Upload the code to the micro:bit

• Return to block coding to see the function

• Test the code in a simulator

• Restart the micro:bit
