You can choose between two options: "Windows Installer" or "Windows ZIP file". The installer option will guide you through the setup process and create shortcuts on your desktop and start menu. The ZIP file option will allow you to extract the software anywhere on your computer and run it as a portable application. We recommend the installer option for most users.
Download the file and run it. Follow the instructions on the screen and accept the license agreement. You can choose the components you want to install, such as drivers, shortcuts, and associations. You can also choose the installation location, or leave it as default.
Wait for the installation to finish and click on "Close". You can now launch Arduino IDE from your desktop or start menu.
Mac installation guide
Go to the and click on the Mac OS X option under the "Arduino IDE" section.
Download the file and open it. Drag and drop the Arduino application into your Applications folder.
The first time you run Arduino IDE, you may see a warning message that says "Arduino" can't be opened because it is from an unidentified developer. To fix this, go to System Preferences > Security & Privacy > General and click on "Open Anyway". Alternatively, you can right-click on the Arduino application and select "Open".
You may also need to install some drivers for your Arduino board to be recognized by your computer. To do this, go to Tools > Board > Boards Manager and search for the name of your board. Click on "Install" and wait for the installation to finish.
Linux installation guide
Go to the and click on the Linux option under the "Arduino IDE" section.
You can choose between two options: "Linux 32 bits" or "Linux 64 bits". Choose the one that matches your system architecture. You can also choose between "Linux ARM 32 bits" or "Linux ARM 64 bits" if you are using a Raspberry Pi or another ARM-based device.
Download the file and extract it to a folder of your choice.
To run Arduino IDE, you need to make the install.sh script executable. To do this, open a terminal window and navigate to the folder where you extracted Arduino IDE. Then type: chmod +x install.sh and press enter.
Then run the script by typing: ./install.sh and press enter. This will create a desktop shortcut and a menu item for Arduino IDE.
You may also need to add yourself to the dialout group to access the serial port of your Arduino board. To do this, type: sudo usermod -a -G dialout $USER and press enter. You will need to log out and log back in for this change to take effect.
How to use Arduino IDE
Now that you have installed Arduino IDE on your computer, you are ready to use it for your Arduino projects. Here are some basic steps to get you started:
Overview of the interface and tools
When you launch Arduino IDE, you will see a window with several elements:
The menu bar at the top provides access to various commands and options, such as file management, board selection, code uploading, serial monitor, etc.
The toolbar below the menu bar provides shortcuts to some of the most common commands, such as verify, upload, new, open, save, etc.
The code editor in the center is where you write your code, also known as sketch. It has line numbers, syntax highlighting, auto-completion, code folding, and error checking features.
The message area at the bottom shows the output of your code verification or upload process, as well as any errors or warnings that may occur.
The status bar at the very bottom shows some information about your board, such as port number, board type, and memory usage.
How to write and upload code to Arduino boards
To write and upload code to your Arduino board, follow these steps:
Connect your Arduino board to your computer with a USB cable. Make sure the board is powered on.
Select your board type from Tools > Board. For example, if you are using an Arduino Uno, select "Arduino Uno".
Select your port number from Tools > Port. For example, if you are using Windows, it may be something like "COM3". If you are using Mac or Linux, it may be something like "/dev/ttyUSB0".
Type your code in the code editor. You can use one of the examples from File > Examples to get started, or write your own code from scratch. A basic sketch consists of two main parts: the setup() function and the loop() function. The setup() function runs once when the board is powered on or reset, and it is used to initialize variables, pin modes, libraries, etc. The loop() function runs repeatedly and it is used to perform the main logic of your code.
Verify your code by clicking on the check mark icon on the toolbar, or by pressing Ctrl+R on your keyboard. This will compile your code and check for any errors or warnings. If there are any, they will be displayed in the message area. You can fix them and verify again until your code is error-free.
Upload your code by clicking on the right arrow icon on the toolbar, or by pressing Ctrl+U on your keyboard. This will send your code to your Arduino board via the USB cable. You will see some messages in the message area indicating the progress of the upload process. When it is done, you will see a message that says "Done uploading".
Your code is now running on your Arduino board. You can see the output of your code on the serial monitor, which you can open by clicking on the magnifying glass icon on the toolbar, or by pressing Ctrl+Shift+M on your keyboard. The serial monitor allows you to view and send data to and from your board via serial port.
How to troubleshoot common errors and issues
Sometimes, you may encounter some errors or issues when using Arduino IDE. Here are some of the most common ones and how to fix them:
If you get an error that says "avrdude: stk500_getsync(): not in sync: resp=0x00" or something similar, it means that Arduino IDE cannot communicate with your board. This could be due to several reasons, such as a wrong board type or port number, a faulty USB cable or port, a corrupted bootloader, or a conflict with another program that uses the same port. To fix this, you can try the following solutions:
Make sure you have selected the correct board type and port number from Tools > Board and Tools > Port.
Try using a different USB cable or port.
Try pressing the reset button on your board before uploading your code.
Try closing any other program that may use the same port as Arduino IDE, such as Bluetooth devices, modems, etc.
Try burning a new bootloader to your board using another Arduino board as an ISP (In-System Programmer). You can find more information on how to do this .
If you get an error that says "error: expected ';' before '}' token" or something similar, it means that you have a syntax error in your code. This could be due to missing or extra characters, such as semicolons, brackets, quotes, etc. To fix this, you can try the following solutions:
Check your code carefully and make sure you have closed all the brackets, quotes, and semicolons properly.
Use the auto-format feature of Arduino IDE by pressing Ctrl+T on your keyboard. This will indent your code and make it easier to spot any errors.
Use the find feature of Arduino IDE by pressing Ctrl+F on your keyboard. This will allow you to search for specific characters or words in your code.
If you get an error that says "fatal error: SomeLibrary.h: No such file or directory" or something similar, it means that you are trying to use a library that is not installed or included in your code. A library is a collection of code that provides some functionality for your sketch, such as controlling a sensor, display, motor, etc. To fix this, you can try the following solutions:
Make sure you have installed the library that you want to use from Tools > Manage Libraries. You can search for the name of the library and click on "Install".
