If you'd like to learn more about MakeCode, this guide is a good place to start.
To upload code, follow these instructions:
1) Connect your Circuit Playground Express to your computer using a micro USB cable and press the small reset button in the center of the board. All the LEDs will flash red briefly, then turn green. Your computer should now show a removable drive called CPLAYBOOT.
2) Click the Download button in the code window below to download the .UF2 file to your computer.
3) Now drag and drop the .UF2 file onto the CPLAYBOOT drive in your computer's file explorer or finder.
The drive will automatically eject itself (your computer may give you a "failed to eject drive correctly" error, you can ignore this). The code is now on your Circuit Playground Express and ready to run!

pick random bubble to make the game more or less certain.
Below the rest of the code, you will notice two blocks, one adding a function to button A, and one to button B.
These buttons will allow you to easily open and close the door using the servo motor, important for reloading the piñata with candy.
Problem: My motor doesn't move!
Solution: Make sure that your Circuit Playground Express is connected to a power source (anywhere between 3V-5V is safe). If you're using a AAAx3 battery pack, check that the switch on the battery pack is set to "ON". If you are using the LiPo battery, be sure it is fully charged using the charger in the Featured Products.
Problem: My Circuit Playground Express doesn't show up as CPLAYBOOT
- Be sure you have a Circuit Playground Express. The Circuit Playground Classic will not work with MakeCode.
- If you get a drive named CIRCUITPY instead, press the reset button twice in succession to get to CPLAYBOOT.
- Some USB cables are "charge-only" and won't pass data. Try using a different USB cable and try using a different USB port on your computer.
- With the Circuit Playground Express plugged into your computer with a micro USB cable, click the small reset button in the center of the board. The lights should all turn green. If they don't, try double-clicking the reset button.

If you ever need to convert your Circuit Playground Express back to CircuitPython mode, you can do so by downloading the appropriate .UF2 file from CircuitPython.org and dragging it over onto your CPLAYBOOT drive. See this guide page for the step-by-step instructions.
