The prevalence of inexpensive GPS shields for the Arduino platform has seen a plethora of clock, geocaching and other projects demonstrated by many enthusiast. However we don't see to many distance calculators - until now.
Jacob Dobson has built a neat version that's easy to use and works well, by simply indicating the starting and finishing points using buttons on the attached LCD shield, the distance calculator will give you the distance between the two points, as shown in the following video demonstration:
Although originally designed for sports use, it's a good tool to calibrate other measurement tools or just increase the accuracy of existing measurements. To get started, visit the project page. And for more, we're on facebook, Google+, and twitter - 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, GPS shields and more - 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. For more information including a sample chapter and table of contents, visit the book page.
