Have an ancient cell phone sitting around? Tinkernut shows you how to make use of it by turning it into a smartwatch with an Arduino brain.
Using a Nokia 1100, Tinkernut walks you through pulling apart the old phone, connecting it to the Arduino, and setting up the software required to make this sucker work. By the end of the three-part series, youâll have a bulky, but totally DIY watch that can connect to your phone to show you notifications and other small details. It sure ainât pretty, but as a base for your own project, itâs one of the more clever DIY smartwatches weâve seen. Head over to Tinkernut for the full guide.
