Adafruit IO Example Secrets
This example requires you to provide your Wi-Fi credentials, and your Adafruit IO
username and key. To do this, you'll want to create a secrets.py file on your CIRCUITP
Y drive.
To obtain your Adafruit IO key, follow the initial steps on this pageī¤().
For information on how to structure your secrets.py file, and what information to add
to it, check out the Secrets File section on the CircuitPython Internet Test pageī¤().
Adafruit IO Example Code
To run this example, you need to first install the NeoPixel, Adafruit IO, and Adafruit
MiniMQTT libraries into the lib folder on your CIRCUITPY drive. Then you need to
update code.py with the example script.
Thankfully, we can do this in one go. In the example below, click the Download
Project Bundle button below to download the necessary libraries and the code.py file
in a zip file. Extract the contents of the zip file, and copy the entire lib folder and the c
ode.py file to your CIRCUITPY drive.
