Year 7 - Computing

Using input and output

Physical computing using the micro:bit

Unit Summary

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.

Lesson Summary

You will learn to write programs that use the output and input features of a physical computing device.

Key Notes

  • Text and images can be displayed by physical computers using arrays of light such as the micro:bit's LED display matrix.
  • Sensors can be used to create programs that respond to their environment.

Vocabulary To Learn

  • Light-Emitting Diode (LED): a component that emits light when electricity flows through it
  • hardware component: a physical part of a computer or device that helps perform its function, such as wires, buttons, or an LED display
  • sensor: a device which detects or measures a physical property such as sound or light

Common Mistakes To Avoid

  • The micro:bit can only show letters and numbers.

3 Quick Questions (With Answers)

1. Describe the system or process from this lesson in clear steps.

Text and images can be displayed by physical computers using arrays of light such as the micro:bit's LED display matrix. Sensors can be used to create programs that respond to their environment.

2. Define this computing term and give one practical example. 'Light-Emitting Diode (LED)'

a component that emits light when electricity flows through it. Add one real device or system example to prove understanding.

3. Correct this common computing misconception.

Mistake: The micro:bit can only show letters and numbers. Correction: The micro:bit's LED display can show more than letters and numbers. It can show shapes, images, and patterns. The display matrix can be programmed to output any desired pattern.
