I was feeling a little adventurous one day and i had a few Arduino R3 boards knocking around. I didn’t really know what to do with them until i came across an article that described a GPS tracker project. Look’s good, i thought and promptly ordered a NEO-6 GPS receiver module that sports a rather nice NMEA (TTL) Uart output.
I checked out the specs and figured i would buy one as a test, just out of curiosity.
We are going to need the following:
1 x Arduino UNO R3 (or Nano / Micro)
1 x 16×2 LCD Display (I2C saves some hassle)
1 x GPS Module with TTL UART Output. (I am using a NEO-6M)
There are many options available for the GPS module. I recommend ANY module that supports UART TTL Level output on the data pins. The NEO-6M can be powered directly from a 5volt supply due to the GPS Decoder Board having a 3.3Volt level shifter. If your GPS module does not have an onboard voltage regulator, please use a 3.3volt supply ONLY
Connect the hardware as shown:
