All running on hardware that fits in your palm and costs a fraction of commercial tracking systems.That is exactly what you will build in this course — from the very first connection to a fully deployed real-time vehicle tracking system powered by ESP32.This Is a Build-It-Yourself Course. Not a Theory Lecture.Every section moves you forward with hands-on implementation. You will wire real components, write real code, and watch your vehicle's location update live on a map — using a system you designed yourself.No prior experience needed. If you can use a computer, you can build this.What You Will Build:A complete real-time vehicle tracking system that:Reads live GPS coordinates from a GPS moduleDisplays location data on a connected OLED screenSends real-time data to an IoT dashboardVisualizes live vehicle movement on Google MapsRuns entirely on ESP32 — no external computer requiredWhat You Will Learn — Section by Section:Introduction to ESP32 Understand the most powerful and versatile microcontroller in the IoT space. Learn its specifications, GPIO pin structure, power requirements, and exactly why it is the right choice for real-time tracking applications.ESP32 Setup and Testing Install the IDE, configure drivers, and run your first program on the ESP32 board. You will verify your hardware is working perfectly before writing a single line of project code.OLED Display Programming Install the required drivers, wire the OLED display to ESP32, and program it to show custom real-time data. Understanding each component independently ensures seamless integration later.
