While visiting the north part of Scotland, I came across websites and apps that shows alerts for the Aurora (northern lights). After reading Uri Shaked article "How to Connect Your T-Shirt to Slack Using Arduino", I decided to create an Aurora alerts ring, using WeMos board and 24 NeoPixel LED and gets the alerts from AuroraWatch UK API.
I won’t explain here how the software works, you can read Shaked article for that.
For this project you will need:
I used 24 NeoPixel LED but you can use any type of display you like. Gust modify the code as needed.
I decided to frame it all so I can put it on a wall. And use a standard USB cable to power it up.
