Create Your Own Clock With Pedometer, Temperature, Compass and More.
Smartwatches are great, but they don’t reflect the spirit of “do it yourself”. Instructables user benhur.gonvalves shows you how to build a small smartwatch using Arduino.
To make one, you will need an Arduino Pro Mini, some sensors, and some general knowledge of PCBs. The end result is a watch that tracks your steps, checks temperature and altitude, and acts like a compass when you need it. As you’d expect from a prototype, it’s not the prettiest thing on the planet, but you’ve got the courage to tweak it to suit your own style.
