Thanks to the compact format of our LeoStick Arduino Leonardo-compatible board, they can be found in all sorts of useful situations. One of these has been described by Freetronics forum member plainolddave who has used a LeoStick to solve a common problem - stopping the screen-saver of a PC coming on when running software that doesn't need constant user input.
As the LeoStock can emulate a USB HID such as a keyboard or mouse, the sketch simply emulates the "wiggle" of a USB mouse and thus preventing the screen-saver from starting. The LeoStock can easily be added or removed when required and nearly solves the problem without any extra hardware. You can review the sketch and make your own from the project github page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
Need a small Arduino-compatible for use with your own projects? Then check out 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.
