Getting Started with the micro:bit
Getting Your Program Onto Your micro:bit
You've built your first program in MakeCode, and it works in your simulator. Now, how do you get it onto your micro:bit?
Download Your Program
Once you are happy with your program, you can click the Download button in MakeCode.
This will download your program file to your standard download location, probably the Downloads folder on your computer, or whatever location you have set in your download preference.
You then simply click and drag your program file from its download location to your micro:bit drive, which shows up as an external device.
Your micro:bit will flash for a few seconds, and then your program will start automatically. Yes! Win!
