  1. /*
  2. The NEO-M8N GPS module communicates via UART. Here's an example of how to use the NEO-M8N GPS module with an Arduino to read and parse GPS data using the TinyGPS++ library. You can install the library using the Arduino Library Manager.
  3.  
  4. Connect the NEO-M8N GPS module to your Arduino as follows:
  5.  
  6. VCC to 5V or 3.3V (depending on your GPS module's voltage range)
  7. GND to GND
  8. TX to GPS_RX_PIN (4 in this example)
  9. RX to GPS_TX_PIN (3 in this example)
  10. Upload the complete code to your Arduino and open the Serial Monitor. The GPS module should start sending data. Once it gets a GPS fix, it will display the latitude and longitude values.
