Download

Click the big pink Download button.

This will save your program as a file in the Downloads folder on your computer. Using your computer’s file explorer, open the Downloads folder, you should see a file there called circuitplayground-Untitled.uf2. This is your program.

Now, check the Adafruit Circuit Playground Express board that is plugged into your computer via the USB cable, and make sure that all the lights are green. If they are not green, press and release the RESET button in the middle of the board until all the lights turn green.

Using your computer’s file explorer, you should see the Adafruit Circuit Playground Express show up as a USB drive called CPLAYBOOT. Drag and drop (or copy and paste) your circuitplayground-Untitled.uf2 program file from the Downloads folder into the CPLAYBOOT drive.

That’s it! Congratulations on Making and Coding your very own indestructible Legendary Gauntlets.
