Adafruit AirLift Shield ESP32 User Manual

# This file is where you keep secret settings, passwords, and tokens!
# If you put them in the code you risk committing that info or sharing it
secrets = {
'ssid' : '_your_ssid_',
'password' : '_your_wifi_password_',
'timezone' : "America/Los_Angeles", # http://worldtimeapi.org/timezones
'aio_username' : '_your_aio_username_',
'aio_key' : '_your_aio_key_',
}
Next, set up an Adafruit IO feed named test
If you do not know how to set up a feed, follow this page and come back when you've set up a feed
named test . (https://adafru.it/f5k)
We can then have a simple loop for posting data to Adafruit IO without having to deal with connecting or
initializing the hardware!
Take a look at your test feed on Adafruit.io and you'll see the value increase each time the CircuitPython
board posts data to it!
