Guide to the Arduino Mini
To get started with the Arduino Mini, follow the directions for the regular Arduino on your operating system (, , ), with the following modifications:
· Connecting the Arduino Mini is a bit more complicated than a regular Arduino board ( for instructions and photos).
· You need to select Arduino Mini from the Tools | Board menu of the Arduino environment.
· To upload a new sketch to the Arduino Mini, you need to press the reset button on the board immediately before pressing the upload button in the Arduino environment.
Information about the Arduino Mini
The microcontroller (an ATmega328) on the Arduino Mini is a physically smaller version of the chip on the USB Arduino boards, with the following small difference:
· There are two extra analog inputs on the Mini (8 total). Four of these, however, are not connected to the legs that come on the Arduino Mini, requiring you to solder wires to their holes to use them. Two of these unconnected pins are also used by the Wire library (I2C), meaning that its use will require soldering as well.
Also, the Arduino Mini is more fragile and easy to break than a regular Arduino board.
· Don't connect more than 9 volts to the +9V pin or reverse the power and ground pins of your power supply, or you might kill the ATmega328 on the Arduino Mini.
· You can't remove the ATmega328, so if you kill it, you need a new Mini.

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.)
.
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.
or with Windows7, Vista, or XP:
· 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)"
· 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's driver file named "Arduino UNO.inf"
· Windows will finish up the driver installation from there.

Installing drivers for the , , or 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. (Really, it works!)
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. Click next.
· 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 drivers/FTDI USB Drivers directory of the Arduino distribution. (The latest version of the drivers can be found on the .) 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 Ports section; that's the Arduino board.
