This course will teach you how to build your own GPS-Tracker using an Arduino, a GPS-Module, and an LCD-Shield.You will learn how coordinate systems work. Two dimensional and three dimensional. I will show you how these coordinate systems are applied to earth and how you can use them for navigation. Then i will show you what satellites are, where they are and what kinds of purposes they serve. After that you will learn how you can use four satellites to locate yourself on the surface on the earth. After that i will show you the Arduino basics. This goes from explaining what an Arduino is to setting up the IDE on your computer, showing you how the Syntax and Libraries work and the important pins and their functions. From that we'll move on the the LCD shield.That chapter will contain the working principle of an LCD screen, the pins of the screen and their functions, how to digitally store something as text, creating your first, own text and reading the button input of your shield. Chapter five will be about learning how your GPSmodule communicates, how you can connect it to the Arduino and how you can write a basic script using the gps library. In the last chapter we will be putting everything together. That means writing the final program and soldering everything together. In case you don't care about the theory and strictly want to build it, that is also possible. Theory and practice for each topic is split up in seperate lessons.
