Today you are coding with the micro:bit. You will build a wearable step counter you can walk with, watch the count on the LEDs, and check how accurate it is.
You already know how to open a MakeCode project and send code to a micro:bit. We will predict, build step by step, run it on the board, investigate the count, modify it, and test again.
What do you think the micro:bit can sense so it knows you took a step?
Go to the makecode.microbit.org website and create a new project.
Go to the Makecode.com Microbit website using the link below and click on the 'New Project' button underneath the 'My Projects' heading.
https://makecode.microbit.org/
Install the micro:bit app on your iPad or tablet.
Open the app, tap 'Create code' and then create a new project.
We will need to remember the amount of steps we've taken so we will create a variable called 'steps'.
In the Variables toolbox, create a new variable by clicking the 'Make a Variable' button.
Once you click this button a box will appear asking what you want to call your variable. Give it a name that reminds you what you will be using it for. For example, if you wanted to keep track of your score in a game, you would create a variable called 'score'.
When we start the 'steps' should be 0. Add the following code:
let steps = 0
