Micro:bit Programming Quiz

What is the first step to start coding a Micro:bit?

• Open a text editor

• Visit the MakeCode website

• Connect the Micro:bit to Wi-Fi

• Install special software

Answer explanation

The first step to start coding a Micro:bit is to visit the MakeCode website. This platform provides the necessary tools and resources to begin programming the Micro:bit effectively.

What is the purpose of debugging in programming?

• To create new variables

• To correct errors in the code

• To make the code run faster

• To add comments to the code

Answer explanation

The purpose of debugging in programming is to correct errors in the code. This process helps identify and fix bugs, ensuring the program runs as intended.

What type of device is a Micro:bit?

• A smartphone

• A calculator

• A tiny computer

• A game console

Answer explanation

The Micro:bit is designed as a tiny computer for educational purposes, allowing users to learn programming and electronics. It is not a smartphone, calculator, or game console, making 'a tiny computer' the correct choice.

What do the buttons on a Micro:bit do?

• They display outputs

• They provide inputs

• They run processes

• They power the device

Answer explanation

The buttons on a Micro:bit are used to provide inputs, allowing users to interact with the device by pressing them. They do not display outputs, run processes, or power the device.

What is an example of an OUTPUT on the Micro:bit?

• Pressing a button

• Displaying a pattern on LEDs

• Storing a variable

• Writing an IF statement

Answer explanation

Displaying a pattern on LEDs is an output action on the Micro:bit, as it shows visual feedback. In contrast, pressing a button is an input, while storing a variable and writing an IF statement are programming actions, not outputs.

Which programming structure is used for making decisions?

• Loops

• Variables

• Functions

• IF statements

Answer explanation

IF statements are used to make decisions in programming by evaluating conditions and executing code based on whether those conditions are true or false. Other options like loops, variables, and functions do not serve this purpose.

What is iteration in programming?

• Storing data

• Debugging code

• Repeating code

• Displaying outputs

Answer explanation

Iteration in programming refers to the process of repeating code, allowing a set of instructions to be executed multiple times. This is essential for tasks that require repetitive actions, making 'Repeating code' the correct choice.

How many times can a loop run?

• It depends on the programmer’s choice

• Always 10 times

• Only once

• Until the Micro:bit is turned off

Answer explanation

The number of times a loop can run is determined by the programmer's choice, such as the loop's condition or the number of iterations specified. Therefore, the correct answer is that it depends on the programmer’s choice.

What are variables used for?

• Storing information

• Displaying outputs

• Providing inputs

• Debugging programs

Answer explanation

Variables are primarily used for storing information, allowing programs to keep track of data that can be used and manipulated throughout the code. This makes 'Storing information' the correct choice.

How should variable names be chosen?

• Randomly

• As short as possible

• Descriptive and clear

• Written in capital letters only

Answer explanation

Variable names should be descriptive and clear to enhance code readability and maintainability. This helps others (and yourself) understand the purpose of the variable, making the code easier to work with.
