The CIRCUITPY Drive

https://learn.adafruit.com/adafruit-esp32-s2-feather/the-circuitpy-drive

The CIRCUITPY drive is where your code and the necessary libraries and files will live. You can edit your code directly on this drive and when you save it, it will run automatically. When you create and edit code, you'll save your code in a code.py file located on the CIRCUITPY drive.

With a fresh CircuitPython install, on your CIRCUITPY drive, you'll find a code.py file containing print("Hello World!") and an empty lib folder.

CircuitPython looks for code.py and executes the code within the file automatically when the board starts up or resets. Following a change to the contents of CIRCUITPY, such as making a change to the code.py file, the board will reset, and the code will be run.

CircuitPython Libraries needed for the Pavilion Project

Libraries are stored on your CIRCUITPY drive in a folder called lib.

You can download the latest Adafruit CircuitPython Library Bundle here: https://circuitpython.org/libraries

Download Bundle for Version 7.x

The libraries that will be needed for the Pavillion project are listed below. Copy them from the bundle and include them in your lib folder.

Adafruit Platform

You will need to create an account on adafruit.com

Secrets.py File

It allows you to store your WiFi network's SSID and password, along with other sensitive information, separately from your main program, so that you don't accidentally share your info when sharing your code.

Head to io.adafruit.com and simply click the View AIO Key link on the left-hand side of the Adafruit IO page to get this information.

You will need your network information, as well as an Adafruit IO account. Your Adafruit AIO information and your location will also be placed in the file.

Using Mu or any text editor, you should add your Adafruit IO Username and Adafruit IO Key to the secrets.py file.

Once you have logged into your account, there is information you'll need to place in your secrets.py file: Adafruit IO username, Adafruit IO key, broker, MQTT port, MQTT username, and MQTT password in the secrets.py file.

Your secrets.py file should look similar to this:

secrets = {

    ‘SSID’ : ‘your SSID here’,
    ‘password’ : ‘Your password here’,
     ‘aio_username’ : ‘your aio username’,
    ‘aio_key’ : ‘your aio key’,
    ‘broker’: “io.adafruit.com” ,
    ‘mqtt_port’: 8883,
    ‘mqtt_username’: ‘your aio_username’,
    ‘mqtt_password’: ‘your aio_key’,
    }

Save your secrets.py file in your CIRCUITPY root file
