Lesson details

Key learning points

  1. Design a physical computing project that solves a problem for a specific audience using available resources.
  2. Break down a complex task into smaller, simpler steps.

Keywords

  • Audience - the intended users of the physical computing project

  • Decompose - the process of breaking down a large task into several subtasks

Common misconception

Planning a physical computing project slows you down and does not need to be thought of before starting what you want to make.

A plan helps you think through the steps, figure out what you need, and make sure your project turns out how you want it to. If you don't plan, you could end up making mistakes that will mean your project doesn't turn out how you would like.

6 Questions

Q1.
Why might someone think planning isn’t necessary?
They want the project to succeed.
They enjoy testing components.
Correct answer: They underestimate its importance.
They are focused on decomposition.
Q2.
Why is it important to consider the audience when designing a physical computing project?
It guarantees the project will look good.
It makes the project easier to build.
It ensures the project uses expensive components.
Correct answer: It ensures the project solves the problem effectively for its users.
Q3.
What word means to simplify a problem into smaller parts?
Correct Answer: decompose, decomposition, decomposing
Q4.
Match the terms to their correct description.
Correct Answer:audience,the intended users of a physical computing project
tick

the intended users of a physical computing project

Correct Answer:decompose,breaking a large task into smaller, manageable subtasks
tick

breaking a large task into smaller, manageable subtasks

Correct Answer:proposal,a detailed plan outlining the goals and steps of a project
tick

a detailed plan outlining the goals and steps of a project

Q5.
Which of the following is an example of decomposing a task?
writing a single complex program all at once
Correct answer: breaking a program into small tasks like setting up LEDs and buttons separately
ignoring small tasks and focusing only on the final outcome
testing components only after everything is built
Q6.
Arrange the steps for planning and completing a physical computing project in the correct order.
1 - Identify the audience and the problem to solve.
2 - Create a proposal outlining goals and resources.
3 - Decompose the problem into smaller tasks.
4 - Build and integrate components into the final solution.
5 - Test and refine each part of the project.
