5) Use it!
For this video we got those numerals pouring out of the Digi XBee by using the Remote Digi XBee AT Settings feature of the XBee Internet Gateway. It’s an easy way to switch the LED segments on and off from the Internet. You could also use the Arduino XBee Library to run a local display wirelessly.
Now you can create a counter that shows how far away Friday is, display your current Amazon or Yelp ratings, show the current flight landing at O’Hare or keep an eye on the temperature in your restaurant’s walk-in freezer. A 7-segment display can keep you, your employees, and your customers in the know!
