 Let's install CircuitPython on this Raspberry Pi Pico and Blink its LED. First, download CircuitPython for Pico from CircuitPython.org. Make sure Pico is disconnected from USB, then hold down the Boot Select button and plug in USB, while continuing to hold the Boot Select button until the RPiRP2 drive appears on your computer. Copy the UF2 file you downloaded onto that drive. The drive will unmount and a new drive, named CircuitPy, will appear. Your Pico is now running CircuitPython. Download and install the Moo editor here. Open up Moo, it'll automatically start with a blank file. In that blank file, type the following code. Save the code to the CircuitPy drive as code.py and overwrite any pre-existing code.py file. And with that, we just made Pico blank.
