How to Program Arduino? How to Use Arduino?

 

In this blog post, we will cover how to get started with Arduino programming for beginners, including how to connect Arduino Uno or other Arduino models to your computer, how to upload software to it, and how to install libraries for the components we will use with Arduino.

 

 

If the Arduino model we are using is original or Arduino Uno R3 DIP, we can directly connect it to the computer with the cable that comes with the product. The computer will automatically recognize Arduino. If your board is Arduino Uno R3 SMD CH340 Chip model, you need to install a driver for the CH340 chip. After this installation, your Arduino will work seamlessly. You can download the driver by clicking here.

 

 

There are several steps we need to follow to upload a program to the Arduino board. First, we need to download the software compatible with our operating system from the official Arduino website. After downloading and installing the software on our computer, we will encounter a screen like the one below. 

 

 

From this screen, we will select our Arduino model under Tools > Board:, and then select the port our Arduino is connected to on the computer under Tools > Port. Then, by clicking the Upload button, we can upload our software to the Arduino board.

 

 

Libraries are compiled versions of the code necessary for hardware components such as sensors, screens, etc., to work with Arduino. For example, when using an LCD screen with Arduino, specific commands need to be written. Later, the screen can work with the Lcd.begin command. However, if these specific codes are not written, the screen will not work. But when a ready-made library is selected, the necessary codes start working in the system, and you only need to give the begin command.

 

To add a library to Arduino, you can use the Sketch > Include Library section as shown in the image on the left. From here, you can use the existing libraries in the Arduino software, download and install a new library from the internet, and write your own library codes.
