There are a huge variety of numeric displays available on the market to interface with our Arduino and compatible boards, however as they increase in size, the price also increases. To get around this problem and to have fun making their own, Hari Wiguna used twenty-eight servos controlled by an Arduino, each of which rotates a segment of a digit - replicating the effect of an LED 7-segment display but at a scoreboard-sized scale. You can see this in action through the following video:
That would make a great clock, or enclosed in a weatherproof case - a neat addition for any sporting club. To learn more about the design check out Hari's website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you've been looking for an approachable, easy to read book to learn about Arduino, or as a gift for someone else - you can't go past "Arduino Workshop - A Hands-On Introduction with 65 Projects” by John Boxall.
Arduino Workshop takes the reader from having zero knowledge about the Arduino platform, electronics and programming and leaves them with the know-how and instructions on everything from blinking an LED, to robotics, wireless data, cellular communications, Internet connected systems and more.
