4. Pairing Microbit with PC, and Download your program

   If the microbit is not plugged in, you will be prompted to save your project. The project is saved into a .hex file.

   After you plug a microbit into your PC, you will see a new drive shown up. That’s the microbit’s storage. One can also download an existing program (.hex file) to microbit by directly dragging the file, and drop it in microbit’s drive. In my case, that’s drive F:

   

   Finally, in the code editor, we can pair our microbit, and download directly from the code editor. To pair, connect microbit, click the purple “Download” button, then select “Pair”

   

   You will see a window pop up asking for permission to connect. Select the BBC microbit, then click connect. After that, you can click “Download” again, and your program will be directly download to the microbit.

   

5. How to open saved project
