GPS trackers are always interesting because they’re so versatile. Location-based services have exploded in the last couple of years, and are poised for more growth as we get further into the 2010’s. At the heart of all of these services is a GPS tracker, and a method of transmitting position data to a server, where a provider (or hacker) can do something useful with it.
Tom Igoe’s blog code, circuits, and construction has posted a tutorial on how to log data from your Arduino and put it into your platform or format of choice. As Tom explains, there’s a few common pathways once you’ve read a sensor or accepted some other form of input:
- Serial transmission to a personal computer, and serial capture to a file.
- Saving data to an SD card mounted on the Arduino.
- HTTP upload to pachube.com via an Ethernet shield or Ethernet Arduino.
