Arduino Program Structure

Arduino / Structure of Arduino Program

Arduino program called “sketch”. Arduino programs can be contains 2 sections. They were
1. Setup( ) function
2. Loop( ) function

Void setup ( ) { }
It is initialize the variables, pin modes, start using libraries, etc and the function runs only once after power up or reset the Arduino and is also called as when a sketch starts.

Void Loop ( ) { }
It is used to control the Arduino board actively. After setup() function starts it is used to loop consecutively for allowing your program to change and respond.
