Begin With Adruino

USB Cable. Standard A-B cable is required. Any length is OK.

    9V DC power plug with 2.1mm barrel plug, positive tip (Optonal)

Assembled Arduino board, preferrably an Uno, Diecimila or Duemilanove (or  whatever the latest version is) but NG is OK too

YOU REQUIRE ABOVE THINGS TO START WITH

Preparing the Arduino!

Take your Arduino out of its protective bag. Look at it and make sure it looks kinda like this:

Diecimila Arduino

Or like this:

NG Arduino

OK, now that you are satisfied that your Arduino looks good, put the rubber bumpers on the bottom of
 the board. This will protect your Arduino from spills and dirty tables. If your table is made out of metal,
 this is essential!

Download & Install Drivers

Depending on which Arduino and which OS you have there are different instructions

Power up! (USB)

Now we are ready for the moment of truth, it's time to plug your Arduino in and power it up. The most
 common way to do this is to plug one end of the USB cable into the Arduino and the other end into a
computer. The computer will then power the Arduino.

The jumper-setting step is only for Diecimila and OLDER arduinos! Make sure the Power Jumper
is set correctly. Right next to the USB jack, there is a jumper with 3 pins. If the jumper is on the two pins
 nearest USB jack, that means you are planning to power the Arduino via the USB cable. If it's on the two
 pins nearer the DC Jack then it means you are planning to power the Arduino using a 9V battery or wall
 adapter.

You'll want it set as shown in the picture above.

Make sure your cable is a A-B cable. One end should be thin, rectangular. The other end should be square.

Plug the thin end into your computer

Make sure that the USB cable is plugged in directly to a computer port. Sometimes monitors or keyboards
 have a USB port you can plug into. Most of the time this is fine, but I strongly suggest you plug it directly
 into the computer as that will eliminate any possible problems. Same goes for USB hubs.
Later on, once you've verified you can power the Arduino and upload sketches no problem, then you can try plugging it into other ports.

Plug the square end into your Arduino

And a few blinking orange lights, on the left side.

If you're plugging it into a Mac or Linux machine, you may not get as much blinking from the orange lights.
 The video is from plugging into a Windows computer.

If no lights or blinking occurs, double check:

• Is the USB cable plugged into the computer and into the Arduino?
• Is the computer on?
• Is the jumper set correctly?
• Try another USB port, USB cable, and computer

If you still can't get it working, your Arduino may be faulty.
Next its time to install the driver! Follow these links for instructions for each of the supported operating
 systems

• Windows

Power up! (9V DC, optional!)

Another way to power up the Arduino is to plug in a battery or wall adapter into the DC jack.
Verify that you have a 9V DC 100-500mA power adapter, with a 2.1mm barrel plug and positive tip.
If the box doesn't have any information about the adapter, you can look for these clues

Make sure the symbol near the bottom of the label is present. It means that the outside of the plug is negative
 and the inside is positive. A center-negative plug will not work with the Arduino.

To verify the DC plug is the right shape, just try plugging it in. If it doesn't fit or is wobbly, it's the wrong
kind.

The jumper-setting step is only for Diecimila and OLDER arduinos! Make sure the Power Jumper
 is set correctly. The jumper should be set so that it connects the two pins close to the DC jack

Plug in the adapter and verify you get the green light!

If not, double check:

• Is the DC adapter plugged in?
• Is the DC adapter the right kind? Check voltage, polarity, plug size, etc.
• Is the jumper set correctly?
• Try another adapter.

If you still can't get it working, your Arduino may be faulty.
