Turn the relay's power switch on by toggling the red switch on top of the relay.
The PyPortal should boot up. The code connects the PyPortal to your WiFi network. Then, it connects to Adafruit IO and subscribes to the feed you set up earlier.
On a web browser, navigate to the Adafruit IO Dashboard you created earlier.
Tap (or click) the Power switch to turn your appliance on.
Toggle the power switch again to turn your appliance off.
That's it! You have successfully connected an appliance to the internet using Adafruit IO.
