This is a series of projects that grew from an introductory set of group workshops that we wrote for a local school's open day to promote their Code Club. Projects 1 to 3 ran for about 20 minutes each, and projects 4 and 5 became workshops at the Code Club where I volunteer (these can each be completed within an hour). These projects were easily completed by kids from ages 7-11. The projects that use multiple micro:bits are scaleable and can work well with any number of micro:bits from 2 to class sets; with the option for kids to collaborate in pairs or larger groups.

Project 2: Shake a Number

There are sensors in the micro:bit that can detect when it is tilted. In this project, we will show different patterns on the micro:bit when it is tilted left and right.

In this project, you will learn:

• How to perform an action based on an event such as shaking your micro:bit
• How to generate a pseudo random number on your micro:bit (pseudo random means a number as random as can be comfortably created with the resources available on our device)

You will need:

• A micro:bit (V1 or V2 is fine) and matching USB cable
• A computer with an Internet connection and a modern web browser

Step 1: Launch your browser, and got to the MakeCode website

• Launch your web browser by clicking on its icon
• Once your web browser loads, click in the address bar at the top and, in the address bar, type in: https://makecode.microbit.org

Step 2: Write your code

• Click on Input and drag across the on shake block - this will let us do something when the micro:bit is shaken
  

• Click on Basic and drag the show number block into the on shake block. From Math drag the pick random 0 to 4 block into the show number block. Now change the 4 to a 6 by clicking on it and typing 6.
  
  Your code should look like this:
  

Step 3: Copy your code to the micro:bit and see it run

• Hold your micro:bit carefully by the edges only, and plug in the micro:bit into the USB port on the computer. Ask for help if you don’t know how to do this. In the bottom left corner, click on the Download button.
  
  

• Find the MICROBIT folder and save the .hex file there. You’ll see a light on the micro:bit flash and stop flashing. When it stops, your code will run. Shake your micro:bit to generate a number between 0 and 6.
  
  Congratulations! You've written another program on the micro:bit!
