1 | Download the Arduino environment
Get the latest version from the
When the download finishes, unzip the downloaded file. Make sure to preserve the folder structure.
Double-click the folder to open it. There should be a few files and sub-folders inside.
2 | Connect the board
The Arduino Uno, Mega, Duemilanove and Arduino Nano automatically draw power from either
the USB connection to the computer or an external power supply. If you're using an Arduino
Diecimila, you'll need to make sure that the board is configured to draw power from the USB
connection. The power source is selected with a jumper, a small piece of plastic that fits onto two
of the three pins between the USB and power jacks. Check that it's on the two pins closest to the
USB port.
Connect the Arduino board to your computer using the USB cable. The green power LED
(labelled PWR) should go on.
3 | Install the drivers
Installing drivers for the
Plug in your board and wait for Windows to begin it's driver installation process. After a few
moments, the process will fail, despite its best efforts
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.
