I wanted to share this geeky device that I built to give me the piece of mind when I have to leave my pup in the car for a short period of time. It uses Adafruit feather board and wing. It's the very first Arduino project I've ever done! I wrote a blog post about it containing all the detail. Hope you like it! Let me know your comments!.
