4 | Connect the board

If you're using a serial board, power the board with an external power supply (6 to 25 volts DC, with the core of the connector positive). Connect the board to a serial port on your computer.

On the USB boards, the power source is selected by the jumper between the USB and power plugs. To power the board from the USB port (good for controlling low power devices like LEDs), place the jumper on the two pins closest to the USB plug. To power the board from an external power supply (needed for motors and other high current devices), place the jumper on the two pins closest to the power plug. Either way, connect the board to a USB port on your computer.

The power LED should go on.

On Windows, the Add New Hardware wizard will open. Tell it not to connect to Windows update and click next.

Here's what the code for the LED blink example looks like.

Select the serial device of the Arduino board from the Tools | Serial Port menu. On Windows, this should be COM1 or COM2 for a serial Arduino board, or COM3, COM4, or COM5 for a USB board.

Push the reset button on the board then click the Upload button in the IDE. Wait a few seconds. If successful, the message "Done uploading." will appear in the status bar.

If the Arduino board doesn't show up in the Tools | Serial Port menu, or you get an error while uploading, please see the troubleshooting suggestions.

A few seconds after the upload finishes, you should see the amber (yellow) LED on the board start to blink.

Learn More

  • Read about the Arduino Environment
  • Learn about the parts of the Arduino board
  • See the tutorials for some example programs. (There are also some examples available in the examples directory inside the arduino directory.)
  • Look up specific Arduino functions and syntax in the reference
  • The Arduino programming language is compatible with the Wiring language allowing porting applications from the Wiring board to Arduino. Please note the differences between the Wiring and Processing languages.
  • If you're having problems, check the FAQ.

1 | Get an Arduino board

The Arduino i/o board is a simple circuit featuring the ATmega8 processor from Atmel. The board is composed of a printed circuit board (PCB) and electronic parts.

There are a few ways to get an Arduino board:

  • buy a ready made board. See how you can buy a board or just the PCB.
    • European distributor
    • US distributor
  • build your own board. If you want you can build your own PCB just by downloading the CAD files from the Hardware page. Extract the .brd file and send it to a PCB manufacturer. Be aware that manufacturing a single pcb will be very expensive. It's better to get together with other people and make 20 or 30 at a time. Since you get the full CAD files you can make your own customised version of Arduino. if you make modifications or fix bugs please send us your changes!
    • purchase parts. purchase the parts from any electronics store. The Serial version in particular has been designed to use the most basic parts that can be found anywhere in the world. The USB version on the other hand requires some advanced soldering skills because of the FTDI chip that is an smd part. Here is a list? of parts for the serial board.
    • assemble the board. We put together a step by step guide on how to build an arduino board. Newbies: never soldered before? afraid of trashing thousands of boards before getting one properly soldered? fear not :) learn to master the art of soldering.
    • program the bootloader. In order for the development environment to be able to program the chip, this has to be programmed with a piece of code called bootloader. See the bootloader page on how to program it on your chip.

Arduino Howto

These are the steps you need to follow in order to be up and running:

  1. Get an Arduino board
  2. Download the Arduino environment
  3. Install the USB drivers
  4. Connect the board
  5. Upload a program

1 | Get an Arduino board

The Arduino i/o board is a simple circuit featuring the ATmega8 processor from Atmel. The board is composed of a printed circuit board (PCB) and electronic parts.

There are a few ways to get an Arduino board:

  • buy a ready made board. See how you can buy a board or just the PCB.

    • program the bootloader. In order for the development environment to be able to program the chip, this has to be programmed with a piece of code called bootloader. See the bootloader page on how to program it on your chip.

2 | Download the Arduino environment

To program the Arduino board you need the Arduino environment.

Download Arduino: From the software page.

For more information, see the guide to the Arduino environment.

3 | Install the USB drivers

If you are using a USB Arduino, you will need to install the drivers for the FTDI chip on the board. These can be found in the drivers directory of the Arduino distribution.

On Windows, you will need to unzip FTDI USB Drivers.zip. Then, when you plug in the Arduino board, point the Windows Add Hardware wizard to the FTDI USB Drivers directory.

The latest version of the drivers can be found on the FTDI website.

4 | Connect the board

If you're using a serial board, power the board with an external power supply (6 to 25 volts DC, with the core of the connector positive). Connect the board to a serial port on your computer.

On the USB boards, the power source is selected by the jumper between the USB and power plugs. To power the board from the USB port (good for controlling low power devices like LEDs), place the jumper on the two pins closest to the USB plug. To power the board from an external power supply (needed for motors and other high current devices), place the jumper on the two pins closest to the power plug. Either way, connect the board to a USB port on your computer.

The power LED should go on.

On Windows, the Add New Hardware wizard will open. Tell it not to connect to Windows update and click next.

Then select "Install from a list or specified location (Advanced)" and 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 location you unzipped the USB drivers to in the previous step. 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. This time, a "USB Serial Port" will be found.

5 | Upload a program

Open the LED blink example sketch: File > Sketchbook > Examples > led_blink.

Here's what the code for the LED blink example looks like.

Select the serial device of the Arduino board from the Tools | Serial Port menu. On Windows, this should be COM1 or COM2 for a serial Arduino board, or COM3, COM4, or COM5 for a USB board.

Push the reset button on the board then click the Upload button in the IDE. Wait a few seconds. If successful, the message "Done uploading." will appear in the status bar.

If the Arduino board doesn't show up in the Tools | Serial Port menu, or you get an error while uploading, please see the troubleshooting suggestions.

A few seconds after the upload finishes, you should see the amber (yellow) LED on the board start to blink.
