This is a very simple sketch to read NMEA strings from a GPS module and display the current ground speed. In addition, it logs position information to an SD Card.
- tinygps
- LedControl
- Arduino UNO or Nano. It should work on the later high-powered versions of these boards, but I haven't tested it
- Serial GPS Receiver Module. All the generic modules I have tried worked just fine.
- 8-digit LED display module. Needs to be compatible with the LEDControl Library. Serial interface.
