4. Description
This starter kit is an educational kit based on micro:bit. It comes with basic electronic components, a
breadboard, connection wires and a micro:bit.
5. Getting Started
The programme is written in code blocks, online in the web browser. Open the website www.makecode.com or
https://www.microsoft.com/en-us/makecode?rtc=1 and click the micro:bit icon and click Start Project.
The micro:bit code block opens in a new window. Now, we can start composing the code with code blocks,
which we drag and drop from a code drawer to a code editor.
5.1 What is MakeCode?
Formerly PXT –Programming eXperience Toolkit Editor to write code for the micro:bit.
A graphical, beginner-friendly drag-and-drop code editor similar to Scratch. It works online, in the browser.

You can see the editor is made up of different sections. You make your code in the Code Area, dragging out
blocks from the Code Drawer. You can immediately see your code results in the micro:bit simulator. At the
bottom is where you download and save your project.
Next, we will take a closer look at how to use the Options Bar for doing other things.
Options Bar
Click to create or add a new project.
Import your projects here.
Open up the Blocks interface to write your scripts with the Block editor.
Open up the Javascript interface to type out your script in the Javascript
language.
Handy reference when you are unsure about how the various blocks and functions
work.

Shortcuts to changing project properties. Rename and delete your projects here.
Reset deletes all the projects that you have saved, so be very careful. Most of
the time, you will just want to stick to Delete Project.
Using the LED Bar
We start by writing some code! Each time you select from the Code Drawer, it will list all the codes available to
you. Drag out the show string block and click inside the box to edit.

Say Hello!
The text you have been displaying are called strings.
You can show any integer in the LED screen using show number or any 5x5 pixel image using show leds.
You can also plot one point LED at the time using co-ordinates. Co-ordinate (0,0) is the top left corner.
Joining Blocks
Click and hold the block you would like to join. Drag the block to the target block until a side of the target block
is highlighted. Release and the two blocks are now joined!
Clicking on the first block will move the second; clicking on the second will detach it from the first.

Testing on micro:bit
Connect the micro;bit to your computer using a micro-USB cable.
It will go through a default sequence, asking you to press buttons and play a game. Try it out!
Click Download to translate your script to a hex file and to download it.
If you set Chrome up properly, you will not need this next step. Drag the downloaded hex file to the micro:bit
drive, or right-click and Send To in Windows®.
You have just programmed your very own device!

Step 2
Connect the buzzer to P0 on the BoB.
Connect the ADKeypad to P2 on the BoB.
Make sure for all components that the colour of the wires matches the colour of the pins on the
breakout board.
G = ground = black wire, V (3V3) = power = red wire, S = data or signal pin = yellow wire.
Step 3 –Pre-Coding
Go to http://www.makecode.com. Click onto the micro:bit button to enter the code editor.
We will need to add a package of code to be able to use our kit components. Click on Advanced in the
Code Drawer to see more code sections and look at the bottom of the Code Drawer for Add Package =
Extensions.
The following pop-up window appears.
Now we search for Tinkercademy. Type Tinkercademy in the search box and hit enter.
Click on the Tinkercademy (button) package for downloading and adding it into the Code Drawer.
