The open-source Arduino Software (IDE) (integrated development environment) makes it easy to write code and upload it to the board, it is the way that allows you to communicate with the board and tell it what to do, it runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing and other open-source software; this software can be used with any Arduino board.

So if you are working with Arduino boards, it is important to have the software, so in this article, we will show you how to download and install the IDE.

Getting the IDE:

In this tutorial, we assume you're using an Arduino Uno, Arduino Duemilanove, Nano, Arduino Mega 2560 or Diecimila. If you have another board, read the corresponding page in this getting started guide.

You also need a standard USB cable (A plug to B plug): the kind you would connect to a USB printer, for example. (For the Arduino Nano, you'll need an A to Mini-B cable instead.)

-Download the Arduino Software (IDE): Get the latest version from the download page. When the download finishes, unzip the downloaded file. It is recommended to download the installer.

-Install the drivers: Installing drivers for the Arduino Uno or Arduino Mega 2560 with Windows 7, Vista, or XP:

  • Plug in your board and wait for Windows to begin its driver installation process. After a few moments, the process will fail.
  • Click on the Start Menu, and open up the Control Panel.
  • While in the Control Panel, navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.
  • Look under Ports (COM & LPT). 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)" port and choose the "Update Driver Software" option.
  • Next, choose the "Browse my computer for Driver software" option.
  • Finally, navigate to and select the driver file named "arduino.inf ", located in the "Drivers" folder of the Arduino Software download (not the "FTDI USB Drivers" sub-directory). If you are using an old version of the IDE (1.0.3 or older), choose the Uno driver file named "Arduino UNO.inf"
  • Windows will finish up the driver installation from there.

Installing drivers for the Arduino Duemilanove, Nano, or Diecimila with Windows7, Vista, or XP:

When you connect the board, Windows should initiate the driver installation process (if you haven't used the computer with an Arduino board before), On Windows Vista, the driver should be automatically downloaded and installed.

On Windows XP, the Add New Hardware wizard will open:

  • When asked Can Windows connect to Windows Update to search for software? Select No, not this time, then Click next.
  • Select Install from a list or specified location (Advanced), click next.
  • Make sure that Search for the best driver in these locations is checked; uncheck Search removable media, check include this location in the search and browse to the drivers/FTDI USB Drivers, directory of the Arduino distribution. (The latest version of the drivers can be found on the FTDI website.) Click next.
  • The wizard will search for the driver and then tell you that a "USB Serial Converter" was found. Click finish.
  • The new hardware wizard will appear again. Go through the same steps and select the same options and location to search. This time, a "USB Serial Port" will be found.

You can check that the drivers have been installed by opening the Windows Device Mananger (in the Hardware tab of System control panel). Look for a "USB Serial Port" in the Port’s section, that's the Arduino board.

-Open the blink example: Open the LED blink example sketch from File>Examples>01.Basics>Blink.

Blink example

-Select your board: You'll need to select the entry in the Tools > Board menu that corresponds to your Arduino.

Selecting board

-Selecting an Arduino Uno: For Duemilanove Arduino boards with an ATmega328 (check the text on the chip on the board), select Arduino Duemilanove or Nano w/ATmega328. Previously, Arduino boards came with an ATmega168; for those, select Arduino Diecimila, Duemilanove, or Nano w/ATmega168.

-Select your serial port: Select the serial device of the Arduino board from the Tools> Serial Port menu. This is likely to be COM3 or higher (COM1and COM2 are usually reserved for hardware serial ports). To find out, you can disconnect your Arduino board and re-open the menu; the entry that disappears should be the Arduino board. Reconnect the board and select that serial port.

-Upload the program: Now, simply click the "Upload" button in the environment. Wait a few seconds - you should see the RX and TX LEDs on the board flashing. If the upload is successful, the message "Done uploading." will appear in the status bar. (Note: If you have an Arduino Mini, NG, or other board, you'll need to physically press the reset button on the board immediately before clicking the upload button on the Arduino Software.)

Upload

A few seconds after the upload finishes, you should see the pin 13 (L) LED on the board start to blink (in orange). If it does, congratulations! You've gotten your Arduino up-and-running.
