GPS WITH ARDUINO MEGA 2560
Sebarang pertanyaan/pembelian/bantuan boleh dm saya dia twitter eh:1. Where to buy this SKM53 GPS ?
Memang dari kedai beli SKM53 ni akan dapat cam ni je. Kaki dia tak ngam dengan breadboard & jumper cable. Kena beli jumper cable lain sikit dari biasa.
So, i solder this component with jumper cable.
This how to connect SKM53 to Arduino
VCC > +5V
Gnd > Gnd
TX > digital pin 10
TX > digital pin 10
RX > digital pin 11
Lets go to the next steps.
Software
In this test i use TinyGPS and SoftwareSerial library. I've make a little bit changes with original code to make user easier to search their current position in Google Map.

Just copy and paste this code! Make sure you have added TinyGPS library first.
Check my older post (under ultrasonic sensor post) for tutorial adding library to Arduino IDE!
#include <SoftwareSerial.h>
#include <TinyGPS.h> //include library
long lat, lon;
SoftwareSerial gpsSerial(10, 11); //connect Tx and Rx pin on digital 10 and 11
TinyGPS gps;
void setup() {
Serial.begin(9600); //baud rate with serial monitor
gpsSerial.begin(9600); //GPS baud rate
}
void loop() {
while (gpsSerial.available()) { ///kalau GPS available, Arduino akan mula read
if (gps.encode(gpsSerial.read())) ///Encode signal dari GPS
{
gps.get_position(&lat, &lon); ///lepas Arduino encode signal GPS, baru akan dapatkan global position
float real_lat = (lat/1000000.000); //divide by 1m to make user easier to get their current global postion
float real_lon = (lon/1000000.000);
Serial.print("google: ");
Serial.print(real_lat); //print latitude on Serial monitor (in two decimal places)
Serial.print(", ");
Serial.println(real_lon); //print longitude on serial monitor (in two decimal places)
//////////////////////////////////////////////////////////////////////////////////////////////////
Serial.print("Position: ");
Serial.print("lat: ");
Serial.print(lat);
Serial.print(" ");
Serial.print("lon: ");
Serial.println(lon);
