Function In Arduino
There are two required functions in an Arduino sketch or a program i.e. setup and loop. Other functions must be created outside the brackets of these two functions. The most common syntax to define a function is Function Declaration A function is declared outside any other functions, above or below the loop function.
The function's code goes inside the curly brackets. You can use any Arduino code inside of a function void functionName function code goes here Using a function in a program is known as a function call, or calling a function. To call a function, write the function name, open and closed parentheses, and a semicolon like this
A function is declared outside any other functions, above or below the loop function. We can declare the function in two different ways . The first way is just writing the part of the function called a function prototype above the loop function, which consists of . Function return type Function name
Segmenting the code into different Arduino functions allows the programmer to create modular pieces of code that perform a defined task. In addition, a function in Arduino can be reused in another sketch, so that with time we can have a very complete collection of functions in Arduino that allow us to write code very quickly and efficiently.

What is Function in Arduino. A function is pieces of code that perform a specific task and may return to a value. Instead of repeating the same pieces of code in multple places, The function group it into a single place and then call it at where it needed. Why Use Function.
The typical case for creating a function is when one needs to perform the same action multiple times in a program. For programmers accustomed to using BASIC, functions in Arduino provide and extend the utility of using subroutines GOSUB in BASIC. Standardizing code fragments into functions has several advantages
Calling a Function in an Arduino Sketch. To call a function, use the function name followed by opening and closing parentheses. Finally terminate the statement that calls the function with a semicolon. Load the sketch to an Arduino and then open the terminal window. The sketch prints some text in a box as shown below.
In Arduino, we can declare functions and call them in the main code to work with subroutines. The code is executed line by line, and if we call a function at a line, Arduino will stop at that line and move to that function's declaration. It will execute the code present in the function and then move to the following line in the main code.
