Glowing NeoPixel FeatherWing Indicates “We’ve Got Mail”

Thanks to forums user sketchy from the bitknitting blog for sending this in:

I built (yet another) “we’ve got mail” detector using the Feather M0 RF95 LoRa. The device that tells us we’ve got uses sparkly neopixels behind a translucent enclosure…for some reason just seeing it sparkling makes me smile just for a bit.

I’ve been delighted with the results of my We’ve Got Mail project. Now we know when mail is put into our mailbox. Our mailbox is down the road from our house. There are days when my husband goes down and checks for mail delivery several times. A little exercise is a great thing. But some days it is cold, rainy, and dark.

NOT ANY MORE – when mail comes, the super-dah-dee-duper We’ve Got Mail home device starts to sparkle…a DEFINITE YIPPEE moment…It knows when to sparkle because the Mail Box Puck – which sits inside the mailbox – sends a message to the controller when the mailbox door is opened.
