What is programming ?

Programming

Two ways to write a program!!

Code

Visual

To learn how to write a code we have to learn

operations on variables

The numeric variables like integers, float, and double can apply these operations

Flow Of Execution

#include/define Region

This order get the libraries that have codes that we can use on our project, and you can declare variables here too

Setup Region :

The area that contain the pin mode and the functions that work ones per run

Loop Region :

The area that contain the code that will run for infinity

Flow control

Flow of control, is the order of instructions, and statements are executed or evaluated when a program is running.

Variables

Many programming languages have what are called control flow statements; used to determine what section of code is run in a program at a given time.

A variable is nothing but a name given to a storage area that our programs can manipulate

Flow control are divided into

Loops

For loop

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.

While loop

A while loop statement repeatedly executes a target statement as long as a given condition is true

Do ... While loop

Unlike for and while loops, which test the loop condition at the top of the loop, the do...while loop checks its condition at the bottom of the loop.A do...while loop is similar to a while loop, except that a do...while loop is guaranteed to execute at least one time.

Conditions

Conditioning

Loops

If Statement

An if statement consists of a boolean expression followed by one or more statements.

If ... else Statement

An if statement can be followed by an optional else statement, which executes when the boolean expression is false.

Data Types

int : for integer numbers like 1,2,3,...

double : for float numbers like 1.2 , 2.5, ......

char : used for characters like a,b,c,d,.....

Variable Name :

To set a name for a variable you should follow these conditions

1- variable name can contain letters and digits, but Should Start with letter.

2 There is no spaces in the variable name

3- It can contain only _ as special character

Visual Programming

The nodes are divided into

Is a very simple way for programming via Drag and Drop

Input Nodes

Like this :

Programming via coding

In programming, code is a term used for the statements written in a particular programming language

There are many programming languages

We are using

Output Nodes

Snowball Software

Snowball software uses drag and drop visual programming which is the easiest technique for arduino C language.

Other Features

Flow Nodes
