You'll note here we use a secrets.py file to manage our SSID info. The wifimanager is given the ESP32
object, secrets and a neopixel for status indication.
Note, you'll need to add a some additional information to your secrets file so that the code can query the
Adafruit IO API:
aio_username
aio_key
You can go to your adafruit.io View AIO Key link to get those two values and add them to the secrets file,
which will now look something like this:
