microcontrollers over USB).

General Steps to copy over your program (not specific to any Operating system)

1. Ensure your board is in bootloader mode.

2. Find the .uf2 file generated by MakeCode in your file explorer. Copy it to the "CPLAYBOOT" volume.

3. The status LED on the board will blink while the file is transferring. Once it's done transferring your file, the board

will automatically reset and start running your code (just like in the simulator!)

Windows: Open Windows Explorer (Windows key + E key) and locate the "blinky.uf2" file you generated. It's probably

in your Downloads folder!

You can copy/paste the file to your CPLAYBOOT volume or you can drag/drop it like in the GIF below.

macOS: Open Finder and locate the "blinky.uf2" file. You can copy/paste this file to the "cplayboot" volume or

drag/drop it from the same finder window.

If you want to avoid the copying process: You can download your programs directly to the board. To do this: change

the download location in Chrome (https://adafru.it/wHA), Firefox (https://adafru.it/wHB), Safari (https://adafru.it/wHC), or

Opera (https://adafru.it/wHD)to the main directory of your "CPLAYBOOT" volume.

Running MakeCode that's Already Loaded

If you unplug your board and then plug it back in again to your computer, it may not run the program again

automatically. If it instead shows all green NeoPixels, just press the reset button and your program will start.

On a Mac, you can safely ignore the "Disk Not Ejected Properly" notification that may appear after copying

your .uf2 file.
