In my youtube video, I'm showing you how you can use the app, and visualize the GPS data sent by any microcontroller: https://www.youtube.com/watch?v=jKTF34ZZt1I

The app works in a combination with the Arduino code that I wrote, you can find it on this GitHub repo: https://github.com/Zdravevski/arduino-gps-visualization

It visualizes the data (coordinates) received by various GPS modules available on the market.
The app uses serial communication to receive the commands from the microcontroller, and visualize them on the map.
You can use Arduino, ESP32, or any other board available on the market.

I also have a youtube channel, so I will post a video regarding the app, and how we can use it, you can subscribe to my channel if you want to: https://bit.ly/3FG9hpK

Happy experimenting 😃
