Hello friends! Welcome back to ElectroDuino. This is Arduino Tutorial #3 – How To Program Arduino | Arduino LED Blinking. After understanding How to Download & Install Arduino IDE in Arduino Tutorial #2. In this blog post, we will discuss Introduction to the Arduino Programing Language, How To Program an Arduino in Arduino IDE Software, and as an example, we explain the Arduino LED Blinking code.
The coding language that Arduino uses is very much like C (“see plus plus”), which is a common language in the world of computing. The code you learn to write for Arduino will be very similar to the code you write in any other computer language – all the basic concepts remain the same – it is just a matter of learning a new dialect. Arduino code is written in C with an addition of special methods and functions, which we’ll mention later on. C is a human-readable programming language. When you create a ‘sketch’ (the name given to Arduino code files), it is processed and compiled to machine language.
Arduino Programing Language
It consists of a circuit board, which can be programed (referred to as a microcontroller) and a ready-made software called Arduino IDE (Integrated Development Environment), which is used to write and upload the computer code to the physical board. Arduino programming language can be divided in three main parts: functions, values (variables and constants), and structure. Functions For controlling the Arduino board and performing computations. Extending the Arduino programming language Like most other coding languages, the Arduino language allows you to import external libraries. To put it shortly, a library is a set of prewritten code that provides you with extra features. If the built-in libraries are not enough for you, you can download them online or even write your own.
The Arduino software is open-source. The C/C++ Programing Language used in Arduino IDE to write the Arduino program. It is pretty much the simpler form of C language. Arduino IDE all functions and libraries are written in C/C++. Also, we can use Java programming language to communicate with the Arduino board via serial port communication. But Java will just complicate things in Arduino. So, here We will learn how to create a project in Arduino using the C language.
Sketch − The Arduino program terminology is called “sketch”.
Arduino programming structure
Download sonos s2 mac. The Arduino programming structure consists of two function, one is Setup( ) function and another one isLoop( ) function
Setup( ) function
The setup() function is called when a sketch starts. This function is used to initialize the variables, pin modes, start using libraries, etc. The setup() function will only run once, after power ON or RESET of the Arduino board.
Loop( ) function
After creating the setup() function,then the loop() function is called in sketch. It is also mandatory in an Arduino program. The code inside the loop() function runs again and again. This function does precisely what its name suggests, and loops continuously, also it allowing to change the program and respond. This function is used to actively control the Arduino board.
Arduino LED Blinking
Every programming language has a basic code “Hello, World!”. But in Arduino programming, it is an “LED Blinking” code. You are getting this code in your Arduino IDE example section.
We are using this code to better understanding Arduino programming. Using the Blink sketch, we will turn ON the LED for one second and turn it OFF for one second, it’s continually running. Arduino board has a LED, that is connected to Pin 13 of the Arduino.
Also, we will connect an external LED to the Arduino pin 13, to show “how to connect a LED with Arduino”.

How To Program Arduino – LED Blinking Program/sketch
At first, open your Arduino IDE software. Then open – File >> Example >> Basics >> Blink.
After following the above process, now you reach the blink LED example code window.
Before uploading the program to the Arduino board, we should “Verify or Compile” the code. Click on the first symbol of the Arduino IDE Menu Bar to “Verify or Compile” the code. Now, compiling is started.
After compiling, if your code has no error then you can see the “DONE Compiling” message on the Output panel of Arduino IDE.
Upload code to Arduino board
Now code is ready to upload in your Arduino board. First of all, connect the Arduino board to your computer using the USB cable.
Then go to the Arduino IDE “tool” section for select the “Board” and “port”. In my case Board is “Arduino UNO”, you can choose the Board type according to you Arduino and port is “COM6”, but your port may be different.
All important steps are completed. So, click on the “Upload” button. When uploading is successful you get the “Done Uploading” message on the Output panel of Arduino IDE.
Output Result
As a result, you can see Arduino LED and external LED turn ON for one second and turn OFF for one second, it’s continually running.
