Using Method

Step 1: Connect It

Connect the micro:bit to your computer via a micro USB cable. Your micro:bit will show up on your computer as a drive called 'MICROBIT'. 

Step 2: Program It

Using micro bit MakeCode Block editor https://makecode.microbit.org/, write your first micro:bit code. You can drag and drop some example blocks and try your program on the Simulator in the Javascript Blocks Editor, like in the image below.

Click the JavaScript, you can see the corresponding program code. Shown as below figure.

Step 3: Download It

Click the Download button in the editor. This will download a 'hex' file, which is a compact format of your program that your micro:bit can read. Here you can name the project as LED1, then click “Save”. Shown below.

Once the hex file has downloaded, copy it to your micro:bit just like copying a file to a USB drive. On Windows find the microbit-LED1 file, you can right click and choose "Send To→MICROBIT."


Step 4: Play It

The micro:bit will pause and the yellow 5*5 LED on the back of the micro:bit will display the images while your code is programmed.

You can power it using USB cable or battery. The battery holder need to connect two 1.5V AA batteries. Shown below.
