Once you've finished setting up your QT Py RP2040 with CircuitPython, you can access the code, audio files and necessary libraries by downloading the Project Bundle.
To do this, click on the Download Project Bundle button in the window below. It will download as a zipped folder.

After downloading the Project Bundle, plug your QT Py RP2040 into the computer USB port. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called CIRCUITPY. Unzip the folder and copy the following items to the QT Py RP2040's CIRCUITPY drive.
- lib folder
- code.py
Your QT Py RP2040 CIRCUITPY drive should look like this after copying the lib folder and code.py file.
