Reflecting on a physical computing project

In this unit, pupils will plan, develop, and evaluate a physical computing project. They will break down the project into smaller, easier-to-solve tasks. They will put these plans into action to create a working prototype that they use to evaluate their successes and identify future improvements.

Physical computing using the micro:bit

It can run multiple programs simultaneously.

It can directly connect to the World Wide Web.

It is a small, programmable computer that can execute one program at a time.

Programs for the micro:bit can only be written directly on the device itself.

Which of the following statements about the micro:bit is true?

You can't write programs for the micro:bit; it comes with pre-loaded programs.

Where do you write programs for the micro:bit?

Which component of the micro:bit is used to display information like numbers or letters?

to capture user input and trigger actions in a program

What is the purpose of the buttons on the micro:bit?

Which sensor on the micro:bit can detect how much light is falling on it?

allows communication with other micro:bits

Match the micro:bit component to its function.

Which of the following is an example of an output?

What is the purpose of an 'if statement' in programming?

Which of the following is an example of a condition that can be used in an if statement?

Some program code uses a selection statement with a condition. What will be output?
