I got an Amazon IoT button and made some super simple back that will remind me to clean the pet’s water fountain every n days. I just push the button when I clean the fountain. I would horrify how gross it was before when I would remember to clean it. It’s much more humane now.

Also made Arduino boards that are dedicated timers to blink a light: - 2 minutes to empty my coffee when brewing in a Aeropress. - 24 hours to empty the cat's litter box.

Both of the timers are so simple. It doesn't sound like much, but the hyper focus on the task use case makes it actually improve my life in a small way.
