Behind the scenes, Adafruit IO sends send a command to your board running
WipperSnapper telling it to configure the GPIO pin as a digital output. Your Feather's
page shows the new LED component.
From the page, toggle the LED component by clicking the toggle switch. This should
turn your Feather's built-in LED on or off.
Read a Push-Button
You can also configure a board running WipperSnapper to wirelessly read data from
standard input buttons, switches, or digital sensors, and send the value to Adafruit IO.
Let's wire up a push button to your Feather and configure it with Adafruit IO to publish
a value to Adafruit IO when the button has been pressed or depressed.
In this demo, we show reading the state of a push-button from WipperSnapper.
But the same kind of control can be used for reading switches, break beam
sensors, and other digital sensors.
