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 soon 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.

These all are the circuit diagram for different connections We just flow the circuit diagram and Upload the proper code.

Circuit Diagram 1

In this circuit diagram, we just connect to the GPS Module, GSM Module, And Push Button Only. And I providing the 3.7v dc supply with the help of the LM2596 Step-Down Converter.

GSM Connection

VCC – VCC
Tx – 8
Rx – 9
GND – GND

GPS Connection

VCC – VCC
Tx – RX
GND – GND

Push Button

Pin Number – 3

Code

Before uploading just Change the number

char phone_no[] = "+91xxxxxxxxxx";

1	char phone_no[] = "+91xxxxxxxxxx";

We Just Add the Library and change the Mobile Number then you upload the Code

Demo Of Project

When you press the push button after a few second the GSM send 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.
