Boating and Arduino enthusiast Dave has released another interesting and useful project that's great for small boat users - his "ArduKnot" speedometer. Any avid mariner in busy canals, rivers or canals knows of the speed restrictions and the wrath brought upon by those who notice excessive speed - and this project solves the problem by displaying the speed in knots using large, bright LED display modules. The system simply reads speed data from a GPS receiver, converts it to knots and displays this on the LED numbers using a MAX7219 LED display driver. Once fitted in a weatherproof enclosure, it looks quite the part:
Kudos to Dave for such as useful project. (Check out his LED compass as well). And for more, we're on twitter and Google+, so follow us for news and product updates as well.
When adding your own circuitry for an Arduino-based project such as the ArduKnot system mentioned above, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
