Now that you've wired everything up and added your board to WipperSnapper, it's time to set the device itself up.
The very first thing you'll want to do is make sure that the device is online. Make sure that the box next to the device name is green and says 'Online.'
Call it whatever you want. I chose to call it switch, but anything else should work as well. Finally, set Power Switch Tail Pin to D17.
Now, click on the toggle switch and as you turn it on and off, you should hear a click from the relay and see the electronic device you've plugged in turn on and off.
