Introduction
In this article, I create a powerful GPS tracking device using Arduino and the Sim800L GSM module. This simple yet effective project allows you to track the location of any object in real time using SMS alerts.

SIM800l GSM Module, designed by Simcom. This module operates at a voltage of 3.4v to 4.4v, it is powered directly with a lithium-ion battery and LM2596 step-down converter.
- it also features auto baud rate detection.
- it supports both GSM And GPRS features.
- it comes with an IPX antenna interface that allows switching between a PCB antenna and a suction cup antenna.
Note – The Module is compatible with any 2G-3G SIM card.
Led status indicator
The sim800l module has an LED indicator that shows the network conduction.
Blinking every 1 second – The module is powered on but not connected to the network.
Blinking every 2 seconds – The GPRS data connection is active and ready for data Transfer.
Blinking every 3 seconds – The Module is connected to a network and ready to send/receive SMS messages And Calls.
Neo 6M GPS Module
The Neo-6M GPS module is developed by U-blox.
The GPS Module in Full form is (the Global Positioning System) it uses 31 satellites orbiting Earth to transmit location and date/time.
Led indicator
on the neo-6M GPS Module Board, there’s is a small LED that shows the condition of communication status with satellite:
- No, blinking means the GPS module is searching for satellites.
- Blinking Every 1 Second Means the position is fixed and is connected to the satellite.

3.7v Battery
Push Button
Circuit Diagram
- In this circuit diagram, we connect all the components properly Like the Neo-6M GPS Module connected to the PINs D10 And D11.
- Sim800l GSM Module connected to the Pin Numbers D2 And D3.
- Push button Connected to the Pin Number D5.
NOTE– Here I used the 3.7v lithium-ion Battery to separate the power source of the sim800l GSM Module Because the sim800l module required only 3.4v to 4.4v.
Code
Before uploading the code just add the TinyGPS++ library
Now Select the proper board and upload the Code…..
Now Change the Mobile Number Select the proper board and upload the Code.
