Introduction

GPS System is very commonly used in every field Like Vehicle Tracking, Human Tracking, Ship Tracking, And Bicycle Tracking System. In this tutorial, I will also create a small GPS tracker device to find the latitude and Longitude (GPS Coordinates) And Speed.

Small GPS Tracker uses component’s GPS Neo-6m, Sim800l, Arduino Nano,16×2 LCD Display, Push Button And Buzzer.

Arduino Nano

This one is the Pin Diagram of Arduino nono microcontroller

GSM Sim800l Module

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.

The 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.

GPS Neo-6m 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.

Circuit Diagram

In this circuit diagram, we connect the all components properly Like…

Sim800l GSM Module connected to the PIN D7 And D8.
Neo-6m GPS Module connected to the PIN Rx.
I used Two push buttons and is connected to the PIN D4 And D5.

Here I used the 3.7v lithium-ion battery to power up the whole circuit and also connected the TP4056 Charging Module to charge the lithium-ion battery.

Because the Sim800l GSM Module Is working from 3.6v to 4.2v That’s why I used the Battery if I gave the more power it did not work properly.

Demo Of Project

When you press the push button after a few seconds the GSM sends the text message with the proper GPS coordinates.

Then you receive the call at the same number if you want to receive the call at a different number then change the code.
