GPS-Based Speed Monitor

No More Speeding Tickets

There are many examples on the internet showing how to use a GPS module in a microcontroller project. But what to do with GPS coordinates, except to plot them on a map? I wanted to make something more useful and came up with this GPS-Based Speed Monitor. This device can be used in any vehicle like a car or a boat. It allows you to drive without having your eye on the speedometer and to avoid unpleasant surprises afterward in the mail.

The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
