Launch the Arduino IDE and check the version number in the title bar
To launch the Arduino IDE, you need to find and run the executable file called arduino.exe (on Windows) or Arduino.app (on Mac). If you used the installer option, you can find this file in the folder where you installed the Arduino IDE, or use the shortcuts created by the installer. If you used the zip file option, you can find this file in the folder where you extracted the zip file. When you run the Arduino IDE, you should see a window like this:
You can check the version number of your Arduino IDE in the title bar of the window. It should say "Arduino 1.8.19". If it says something else, you might have downloaded or launched a different version of the Arduino IDE.
How to use Arduino 1.8.19 to program your Arduino board
Connect your Arduino board to your computer with a USB cable
To program your Arduino board, you need to connect it to your computer with a USB cable. The type of USB cable depends on your board model, but it is usually a standard USB-A to USB-B cable or a micro-USB cable. You can find more information about your board and its connection on the official Arduino website. When you connect your board, your computer should recognize it and assign it a port number. You might also see a LED blinking on your board, which means that it is running a default sketch (program) that comes preloaded on it.

Select your board and port from the Tools menu
To communicate with your board, you need to tell the Arduino IDE what kind of board you are using and what port it is connected to. To do this, you need to go to the Tools menu and select Board and Port from the submenus. You should see a list of boards and ports that are compatible with your Arduino IDE version. You need to select your board model from the Board submenu, such as Arduino Uno, Nano, Mega, etc. You also need to select your port number from the Port submenu, such as COM3, COM4, etc. (on Windows) or /dev/tty.usbmodemXXXX, /dev/tty.usbserial-XXXX, etc. (on Mac or Linux). You can also use the Board Info option to see more details about your board, such as its serial number, firmware version, etc.
Write or open a sketch (a program) in the editor window
A sketch is the name of a program that you write for your Arduino board using the Arduino IDE. A sketch consists of two main parts: the setup and the loop. The setup part runs once when you start your board and is used to initialize variables, pins, libraries, etc. The loop part runs repeatedly and is used to perform the main logic of your program. You can write your own sketch from scratch or use one of the many examples that come with the Arduino IDE or the libraries that you install. To write a new sketch, you can go to File > New and start typing your code in the editor window. To open an existing sketch, you can go to File > Open and browse your computer for a file with the .ino extension. You can also use the File > Examples option to see a list of sketches that are organized by category, such as Basics, Digital, Analog, Communication, etc.
Verify (compile) and upload your sketch to your board using the buttons on the toolbar
Before you can run your sketch on your board, you need to verify and upload it. Verifying means checking your code for errors and compiling it into a binary file that your board can understand. Uploading means transferring the binary file from your computer to your board's memory. You can use the buttons on the toolbar to perform these actions. The verify button looks like a check mark and the upload button looks like an arrow pointing right. You can also use the keyboard shortcuts Ctrl+R (or Command+R on Mac) for verifying and Ctrl+U (or Command+U on Mac) for uploading. When you verify or upload your sketch, you will see messages in the console window that tell you the progress and status of your code. If there are any errors in your code, you will see them highlighted in red in the editor window and explained in the console window. You need to fix these errors before you can upload your sketch. If there are no errors in your code, you will see a message that says "Done uploading" in the console window and a LED blinking on your board that indicates that your sketch is running.
Monitor the output of your sketch using the serial monitor or plotter windows
Depending on what your sketch does, you might want to see some output from it on your computer screen. For example, you might want to see some text messages, sensor readings, or graphical data. To do this, you can use the serial monitor or plotter windows that are part of the Arduino IDE. The serial monitor is a window that shows text data that is sent from your board to your computer using serial communication. You can use the Serial.print() or Serial.println() functions in your code to send text data to the serial monitor. You can also use the serial monitor to send text data from your computer to your board using the input field at the top of the window. You need to make sure that the baud rate (the speed of communication) is set correctly on both ends of the communication. You can open the serial monitor by clicking on the magnifying glass icon on the toolbar or by going to Tools > Serial Monitor.
The serial plotter is a window that shows graphical data that is sent from your board to your computer using serial communication. You can use the Serial.println() function in your code to send numerical data to the serial plotter. You can send multiple values separated by commas to create multiple plots. The serial plotter will automatically scale the axes and assign different colors to each plot. You need to make sure that the baud rate is set correctly on both ends of the communication. You can open the serial plotter by clicking on the graph icon on the toolbar or by going to Tools > Serial Plotter.
