i tried giving both 5.5v and 3v the power led will not switch on. i tried to use a program also to observe gps output. i took it outside also
sketch_may19b.ino (695 Bytes)
There is an LED attachd to the timepulse pin (check the device datasheet) but I dont see a power LED.
Timepulse should flash once per second if the GPS has power, is working and gets a fix.

yes that is also not blinking. even if we take it outside
in particular, 7. If you are posting code or error messages, use "code" tags
This is what happens when you do not
if you have a module that is not working, do not say "A GPS" or "the fingerprint sensor". Show us a link to the particular sensor, and a link to the datasheet if available
I did post as an attachment for the code sorry.
#include <SoftwareSerial.h>
#include <TinyGPS.h>
#define RXPIN 4
#define TXPIN 3
#define TERMBAUD 115200
#define GPSBAUD 9600
TinyGPS gps;
SoftwareSerial uart_gps(RXPIN, TXPIN);
void getgps(TinyGPS &gps);
void setup()
{
Serial.begin(TERMBAUD);
uart_gps.begin(GPSBAUD);
Serial.println("");
Serial.println("GPS Shield QuickStart Example Sketch v12");
Serial.println(" ...waiting for lock... ");
Serial.println("");
}
void loop()
{
while(uart_gps.available()) // While there is data on the RX pin...
{
char c = uart_gps.read(); // load the data into a variable...
Serial.print(c) ;
}
}

What serial output do you get?
did you connect GPS TX to Arduino RX?
I suggest using 5V and GND for power (Not the Vin-pn)

using another program i converted this and i can see date and time not location. (time is wrong)
Thats the type of output you would expect if the GPS is indoors or its outdoors and either the GPS is faulty or its antenna is.
Lucky.. "064924.00,V,,,,,,,200520" may 20 2020 @ 6.49 UTC
need 4 satellites to tell position
I bought a new one just in case. Its showing the same thing. I can see date and time not location
Take it outside away from buildings and trees if possible. Set it down and step away.

GPS time is UTC aka Coordinated Universal Time aka Greenwich Mean Time GMT. you have to offset for your time zone
The time put out by the GPS can differ from UTC by a few seconds.
Under good signal conditions the GPS will eventually update to correct the error, but it may not be immediate.
