Welcome to Week 2

Welcome to week 2, watch Lorraine introduce you to this week's core ideas
18.4
Hi, and welcome back to week two on this course on physical computing. I hope you enjoyed week one. We learned a bit about what physical computing actually is. This week, we’re going to talk about something that’s core to physical computing and many things in life, and that is data. We’re going to talk about, what is data? How do we sense it? How can we gather it? How we can manipulate it– should we manipulate it?– and what we do with that data once we have it. I’ll do a short demo of gathering some data and displaying it on a screen using the device we talked

about last week, the BBC micro:bit. We’ll also hear from the chief technology officer of the Microbit Educational Foundation.

Lorraine will talk you through this week’s core idea: data and its role in physical computing.

We will be looking at data in action in physical computing. How it’s recorded from the physical world. Before we move onto the next week of physical computing challenges we want you to have some coding theory under your belt. After we’ve introduced the three main constructs in coding

  • sequence
  • selection
  • iteration

we’ll test your knowledge on how much you’ve learnt. You’ll watch a video from ARM on how to collect data using the BBC micro:bit. Lorraine will do another quick video on data collection and we’ll go through the code for both: applying the theory to the practice.

At the end of the week we’ll talk ethics: what happens when data is corrupt?
