If you're new to Arduino in general, you'll want to check out this tutorial to familiarize yourself with everyone's favorite microcontroller platform.

Note: There are several variants that use the Arduino Uno R3 footprint. Depending on the design, you may need to install additional drivers for your USB-to-serial converter before you are able to able to upload code to your microcontroller. For example, the RedBoard uses an FTDI while the RedBoard Plus uses the CH340.

Atmega16U2 on the Arduino Uno R3	FTDI on the RedBoard	CH340 on the RedBoard Qwiic

Both use different drivers compared to the Arduino Uno R3. Make sure to look closely at your board and its respective hookup guide to determine USB-to-serial converter that is on board. You will probably have either an FTDI or CH340 populated on the board.

Downloading the Arduino IDE

You can download the Arduino IDE from their website. They have installation instructions, but we will also go over the installation process as well. Make sure you download the version that matches your operating system.

The installation procedure is fairly straightforward, but it does vary by OS. Here are some tips to help you along.

Windows

This page will show you how to install and test the Arduino software with a Windows operating system (Windows 10, Windows 7, Vista, and XP).

Go to the Arduino download page and download the latest version of the Arduino software for Windows if you have not already.

Installer

The Windows version of Arduino is offered in two options: an installer or a zip file. The installer is the easier of the two options, just download that, and run the executable file to begin the installation.

When you're prompted to install a driver during installation, select "Install". This will install drivers for Arduino specific boards (like the Uno, Nano, etc.) that you may use in the future.

ZIP

If you choose to download the zip file version of Arduino, you'll need to extract the files yourself. Don't forget which folder you extract the files into! You will need to run the executable Arduino file in the folder to start the Arduino IDE.

When the download is finished, un-zip it and open up the Arduino folder to confirm that yes, there are indeed some files and sub-folders inside. The file structure is important so don't be moving any files around unless you really know what you're doing.

Connecting Your Arduino

Power up your Arduino by connecting your Arduino board to your computer with a USB cable (or FTDI cable if you're using an Arduino Pro). You should see the an LED labeled 'ON' light up. (this diagram shows the placement of the power LED on the UNO).

Drivers for Arduino Uno on Windows

To install the drivers for the Arduino Uno, you will need to plug in your board to your computer's USB port. Once the board is connected, you will need to wait for Windows to begin it's driver installation process. After a few moments, the process will probably fail, despite its best efforts.

Open up a search, type in Device Manager, and hit ENTER.

Look under Ports (COM & LPT) tree. You should see an open port named "Arduino UNO (COMxx)". If there is no COM & LPT section, look under "Other devices" for "Unknown Device. Right click on the "Arduino UNO (COMxx)" or "Unknown device" port and choose the "Update Driver Software" option.

Next, choose the "Browse my computer for Driver software" option

Finally, navigate to the Arduino IDE folder. This should be where you unzipped the Arduino IDE (e.g. it should be similar to the following path with a different version number: C:\Program Files\arduino-1.8.5\drivers). Depending on what version of Windows you have, you may be able to select the Uno's driver file, named "Arduino.inf", located in the "Drivers" folder (not the "FTDI USB Drivers" sub-directory). If you cannot see the *.inf file, it is probably just hidden. You can select the "drivers" folder with the "include sub-folders" option selected instead.

Windows will finish up the driver installation from there! Your computer will enumerate with a COM port. You may see a COM port number depending on what is currently saved in your computer. Try to remember what the number is when uploading. If not, you can always navigate back to the device manager and power cycle the Arduino to determine what number your Arduino enumerated on.

For earlier versions of the Arduino boards (e.g. Arduino Duemilanove, Nano, or Diecimila) check out this page for specific directions.

Drivers for RedBoard on Windows

Depending on your board, there may be different USB-to-serial converters on your board. If you are using a RedBoard you will need to go to the How to Install FTDI Drivers tutorial. If you are using the or RedBoard Qwiic, you will need to go to the How to Install CH340 Drivers tutorial. Make sure to look closely at your board and its respective hookup guide to determine USB-to-serial converter that is on board.

Launch and Blink!

After following the appropriate steps for your software install, we are now ready to test your first program with your Arduino board! Launch the Arduino application. If you disconnected your board, plug it back in.

Open the Blink example sketch by going to: File > Examples > 01.Basics > Blink.

Select the type of Arduino board you're using: Tools > Board > Arduino Uno.

Select the serial/COM port that your Arduino is attached to: Tools > Port > COMxx. In this case it was COM11.

With your Arduino board connected, and the Blink sketch open, press the "Upload" button.

After a second, you should see some LEDs flashing on your Arduino, followed by the message "Done Uploading" in the status bar of the Blink sketch.

If everything worked, the onboard LED on your Arduino should now be blinking! You just programmed your first Arduino!

Troubleshooting

This guide from Arduino has some more details and troubleshooting tips if you get stuck.

Mac

This page will show you how to install and test the Arduino software on a Mac computer running OSX.

Go to the Arduino download page and download the latest version of the Arduino software for Windows if you have not already.

When the download is finished your Mac should automatically un-zip the contents. This will probably in your Downloads folder.

You can leave the program in the Downloads folder or move it into your Applications folder.

Connecting Your Arduino

Power up your Arduino by connecting your Arduino board to your computer with a USB cable (or FTDI cable if you're using an Arduino Pro). You should see the an LED labeled 'ON' light up. (this diagram shows the placement of the power LED on the UNO).

For the Arduino Uno, you do not need to install drivers for Mac! You can skip on down and try uploading a blink sketch!

Drivers for RedBoard on Mac

Depending on your board, there may be different USB-to-serial converters on your board. If you are using a RedBoard you will need to go to the How to Install FTDI Drivers tutorial. If you are using the or RedBoard Qwiic, you will need to go to the How to Install CH340 Drivers tutorial. Make sure to look closely at your board and its respective hookup guide to determine USB-to-serial converter that is on board.

Launch and Blink!

After following the appropriate steps for your software install, we are now ready to test your first program with your Arduino board!

Launch the Arduino application wherever the program is located. If you disconnected your board, plug it back in.

Open the Blink example sketch by going to: File > Examples > 01.Basics > Blink.

Select the type of Arduino board you're using: Tools > Board > Arduino Uno.

Select the serial port that your Arduino is attached to: Tools > Port > xxxxxx. It'll probably look something like "/dev/tty.usbmodemfd131" or "/dev/tty.usbserial-131" but probably with a different number. In this case, it was /dev/cu.usbmodemFD131.

With your Arduino board connected and the Blink sketch open, press the "Upload" button.

After a second, you should see some LEDs flashing on your Arduino, followed by the message "Done Uploading" in the status bar of the Blink sketch.

If everything worked, the onboard LED on your Arduino should now be blinking! You just programmed your first Arduino!

Troubleshooting

Linux

If you are a Linux user, you probably know that there are many different distribution 'flavors' of Linux out there. Unsurprisingly, installing Arduino is slightly different for many of these distributions. Luckily, the Arduino community has done an excellent job of providing instructions for most of the popular versions. Click on the link below that covers your flavor of Linux:

• ArchLinux
• Debian
• Fedora
• Gentoo
• MEPIS
• Mint
• openSUSE
• Puppy
• Pussy
• Slackware
• Ubuntu
• Xandros (Debian derivative) on Asus Eee PC

If the above directions did not work for you, or you don't see your distribution, try this catch-all guide.

You can go to the download page and download the latest version of Arduino for Linux (there are 32-bit and 64-bit versions available) when your system is properly set up.

Connecting Your Arduino

Power up your Arduino by connecting your Arduino board to your computer with a USB cable (or FTDI cable if you're using an Arduino Pro). You should see the an LED labeled 'ON' light up. (this diagram shows the placement of the power LED on the UNO).

ZIP

uname -a

Once you download the zip file version of Arduino, you'll need to extract the files yourself. Don't forget which folder you extract the files into! Once downloaded, open a serial terminal and navigate to the Arduino program folder that was unzipped using the cd command and the folder path. In this case, we downloaded Arduino IDE v1.8.5, 64-bit version for the Ubuntu distribution. The path and folders may be different depending on the version that is downloaded. You may need to use the ls command to navigate.

language:bash
cd /Downloads/arduino-1.8.5-linux64/arduino-1.8.5

Once you are in the Arduino program folder, you'll need to enter the following command in the terminal window to install.

language:bash
./install.sh

At this point, your terminal window will probably look like the following.

When finished, the Arduino IDE will be installed on the desktop!

Drivers for RedBoard on Linux

For the Arduino Uno, you do not need to install drivers for Linux! You may need to change the COM port permissions which will be explained further below. You can skip on down and try uploading a blink sketch!

Drivers for RedBoard on Linux

Depending on your board, there may be different USB-to-serial converters on your board. If you are using a RedBoard you will need to go to the How to Install FTDI Drivers tutorial. If you are using the or RedBoard Qwiic, you will need to go to the How to Install CH340 Drivers tutorial. Make sure to look closely at your board and its respective hookup guide to determine USB-to-serial converter that is on board.

Launch and Blink!

After following the appropriate steps for your software install, we are now ready to test your first program with your Arduino board!

Launch the Arduino application. If you disconnected your board, plug it back in.

Open the Blink example sketch by going to: File > Examples > 01.Basics > Blink.

Select the type of Arduino board you're using: Tools > Board > Arduino Uno.

Select the serial port that your Arduino is attached to: Tools > Port > xxxxxx (it'll probably look something like "/dev/ttyACM0" but probably with a different number)

With your Arduino board connected and the Blink sketch open, press the "Upload" button.

After a second, you should see some LEDs flashing on your Arduino, followed by the message "Done Uploading" in the status bar of the Blink sketch.

Troubleshooting Tip: Having trouble uploading? If you receive the following error when uploading, this could be due to a few reasons. Most likely there is something with the user permissions if you have not used the Arduino Uno on your computer before.

avrdude: ser_open(): can't open device "/dev/ttyACM0" Permission denied Problem uploading to board.

You'll see the output at the bottom of the Arduino IDE.

Try adjusting the permissions by opening a terminal window.

ls -l /dev/ttyACM*

You'll get something similar to the following output.

crw-rw---- 1 root dialout 188, 0 Jul 30 14:14 /dev/ttyACM0

Then type the following command where the <username> is your Linux account user. Make sure to enter your password to change the settings.

sudo usermod -a -G dialout <username>

You'll probably see something similar to the output below with a different username. In this case, our username was "pdev."

You'll need to restart your Linux for the changes to take effect. Since we are already in the terminal window, type the following command to restart your computer. Of course, you can use the GUI as well to restart if you prefer.

sudo reboot

If everything worked, the onboard LED on your Arduino should now be blinking! You just programmed your first Arduino!

Troubleshooting

The Arduino Playground Linux section is a great resource for figuring out any problems with your Arduino installation.

Board Add-Ons with Arduino Board Manager

With Arduino v1.6.4+, a new boards manager feature makes it easy to add third-party boards (like the SparkFun RedBoard, Digital Sandbox, and RedBot) to the Arduino IDE.

To start, highlight and copy (CTRL + C / CMD + C) the text below for the boards manager URL. You'll need this to configure Arduino.

language:bash
https://raw.githubusercontent.com/sparkfun/Arduino_Boards/main/IDE_Board_Manager/package_sparkfun_index.json

Open up Arduino:

• Configure the Boards Manager
  • For Windows and Linux, head to File > Preferences > Additional Boards Manager URLs and paste (CTRL + V / CMD + V) the link
  • For Macs, head to Arduino > Preferences > Additional Boards Manager URLs and paste (CTRL + V / CMD + V) the link
• Click on Tools > Board > Boards Manager...
• Select the Type as "Contributed" from the drop down menu.
• Click on the SparkFun AVR Boards and then click Install.

That's it! Boards are all installed. This also gives you access to all of our library files as well through the built-in Library Manager tool in Arduino. Looking for more information about adding other custom boards? Check out the the following tutorial to install other Arduino cores.
