Finding The Location Status In Arduino Mega 2560

Introduction

In this article I will explain about the correct location of a place where GPS is fixed. After that it will display in the serial monitor and can be very useful for finding location status.

Parts Of List

• Arduino Mega 2560
• GPS
• BreadBoard
• Hook Up Wires

GPS



   Figure1: GPS

• The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 placed satellites.
  
  
• GPS works in any weather conditions, anywhere in the world, 24 hours a day.
  
  
• There are no subscription fees or setup charges to use GPS.

Connection:

• Connect the Gnd and 2nd pin to the Gnd of the Arduino Mega 2560.
• Connect the Vcc to the 5V of the Arduino Mega 2560.
• Connect the 3rd pin to the Digital pin of 3 in the board.
• Connect the 4th pin to the digital pin of 5 in the board.

Programming

#include
// GPS Setup
# define rxGPS 3# define txGPS 5
SoftwareSerial serialGPS = SoftwareSerial(rxGPS, txGPS);
String stringGPS = "";
void setup() {
    pinMode(rxGPS, INPUT);
    pinMode(txGPS, OUTPUT);
    Serial.begin(9600);
    Serial.println("Started");
    // GPS Setup
    serialGPS.begin(4800);
    digitalWrite(txGPS, HIGH);
    // Cut first gibberish
    while (serialGPS.available())
        if (serialGPS.read() == '\r')
            break;
}
void loop()
{
        String s = checkGPS();
        if (s && s.substring(0, 6) == "$GPGGA")
        {
            Serial.println(s);
        }
    }
    // Check GPS and returns string if full line recorded, else false
String checkGPS()
{
    if (serialGPS.available())
    {
        char c = serialGPS.read();
        if (c != '\n' && c != '\r')
        {
            stringGPS = c;
        } else
        {
            if (stringGPS != "")
            {
                String tmp = stringGPS;
                stringGPS = "";
                return tmp;
            }
        }
    }
    return false;
}

Explanation:

In this I have explained the location where GPS is fixed and then you can get information in the serial monitor.
