Show tidal shifts with this Arduino-powered moon clock
If you want to know the tide in your area, you could look it up in the paper, on the Internet, or using an app, but this moon-shaped tide clock provides a unique way to see what’s going on at a glance.
The 3D-printed device uses an Arduino Nano for processing, along with an RTC module to keep accurate time—thus accurate tide predictions. A tiny OLED display provides three info screens, selected via a rocket shaped button taking off of the moon’s surface.
As the clock is meant for education, the moon design will provide a nice reminder of what actually shifts the tides. Arduino code as well as 3D-print files are available on the project’s write-up.
