Arduino 2560 mega and GPS EM-506

Hello

Im trying to get an output from the gps but i believe the gps outputs 3.3 and the mega needs 5volt...

GPS is wired to port TX to arduino pin 19 and RX to 18

code is below

#include <TinyGPS++.h>
#include <SoftwareSerial.h>
/*
This example uses software serial and the TinyGPS++ library by Mikal Hart
Based on TinyGPSPlus/DeviceExample.ino by Mikal Hart
Modified by acavis
*/

// Choose two Arduino pins to use for software serial
// The GPS Shield uses D2 and D3 by default when in DLINE mode
int RXPin = 2;
int TXPin = 3;

// The Skytaq EM-506 GPS module included in the GPS Shield Kit
// uses 4800 baud by default
int GPSBaud = 4800;

// Create a TinyGPS++ object called "gps"
TinyGPSPlus gps;

// Create a software serial port called "gpsSerial"
SoftwareSerial gpsSerial(RXPin, TXPin);

void setup()
{
// Start the Arduino hardware serial port at 9600 baud
Serial.begin(9600);

// Start the software serial port at the GPS's default baud
gpsSerial.begin(GPSBaud);

Serial.println(F("DeviceExample.ino"));
Serial.println(F("A simple demonstration of TinyGPS++ with an attached GPS module"));
Serial.print(F("Testing TinyGPS++ library v. ")); Serial.println(TinyGPSPlus::libraryVersion());
Serial.println(F("by Mikal Hart"));
Serial.println();
}

void loop()
{
// This sketch displays information every time a new sentence is correctly encoded.
while (gpsSerial.available() > 0)
if (gps.encode(gpsSerial.read()))
displayInfo();

// If 5000 milliseconds pass and there are no characters coming in
// over the software serial port, show a "No GPS detected" error
if (millis() > 5000 && gps.charsProcessed() < 10)
{
Serial.println(F("No GPS detected"));
while(true);
}
}

void displayInfo()
{
Serial.print(F("Location: "));
if (gps.location.isValid())
{
Serial.print(gps.location.lat(), 6);
Serial.print(F(","));
Serial.print(gps.location.lng(), 6);
}
else
{
Serial.print(F("INVALID"));
}

Serial.print(F(" Date/Time: "));
if (gps.date.isValid())
{
Serial.print(gps.date.month());
Serial.print(F("/"));
Serial.print(gps.date.day());
Serial.print(F("/"));
Serial.print(gps.date.year());
}
else
{
Serial.print(F("INVALID"));
}

Serial.print(F(" "));
if (gps.time.isValid())
{
if (gps.time.hour() < 10) Serial.print(F("0"));
Serial.print(gps.time.hour());
Serial.print(F(":"));
if (gps.time.minute() < 10) Serial.print(F("0"));
Serial.print(gps.time.minute());
Serial.print(F(":"));
if (gps.time.second() < 10) Serial.print(F("0"));
Serial.print(gps.time.second());
Serial.print(F("."));
if (gps.time.centisecond() < 10) Serial.print(F("0"));
Serial.print(gps.time.centisecond());
}
else
{
Serial.print(F("INVALID"));
}

Serial.println();

Output is 

DeviceExample.ino

No GPS detected

  • Nevermind I found my answer, I need a logic level converter.
