Before heading off to a robot festival, Matt Roy came up with a clever wearable message board device that's easy to build and quite fun. It's based on an Arduino-compatible circuit on some prototyping board and uses the typical MAX7219/LED matrix combination for a display unit. Once completed you can have a variety of text scroll across the display, or create your animations as shown in the following video:
Furthermore by adding Bluetooth it's possible to create a simple Android app to send the required text or commands from a smartphone for more interactive control. Either way, visit the project Instructable page to get started. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
Need a tiny 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.
