One of the best ways to learn about science and technology is by getting your hands dirty and building your own gadgets. This guide by taifur shows you how to build your own dot matrix wristwatch with Arduino. The watch shows time, date, and temperature in two different formats.
You are going to need an Arduino UNO, a 1.2 inch dot-matrix display, a 1.5″ x 1.3″ PCB board, a battery, and a few other parts to get started. You can find more information about the project here.
