Although the market contains a plethora of programmable and connected watches, it's still fun to make your own. An interesting example of this is by Instructables user "kenyer" who used a small Arduino-compatible board, a Nokia LCD module and miscellaneous hardware to fashion his own watch. With only two buttons, it still has many features including time in digital and analogue display, stopwatch, backlight control and more. All the designs and code are supplied so you can replicate it yourself, for example:
If you're making your own miniature Arduino-based project - check out our LeoStick. It's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:
Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
