Basic Sketch Programming Structure For Arduino Ide

Every sketch we will write or use is usually based on the following basic structure: so, the first one is "variables declaration". Where we define the variables we going to use to store values. And for example, over here this is like the "myvar1" and "myvar2".

Next is the "setup" function that is running only once and used for the system setup, "loop" function that is running forever and used as the main program code. And last one is the "custom function" that we can divide our code to more reasonable blocks, something that is very useful while handling a larger program.

Let's start to zoom on each one of them...
