The first thing you will need to do is to login to Adafruit IO and visit the Settings page.
Click the VIEW AIO KEY button to retrieve your key.
A window will pop up with your Adafruit IO. Keep a copy of this in a safe place. We'll need it later.
Creating the Analog Feed
Next, you will need to create a feed called Analog. If you need help getting started with creating feeds on Adafruit IO, check out the Adafruit IO Feed Basics guide.
Adding the Gauge Block
Next, add a new Gauge block to a new or existing dashboard. Name the block whatever you would like, and give it a max value of 1024 and a min value of 0. Make sure you have selected the Analog feed as the data source for the gauge.
