Product details of Arduino UNO R3 compatible With USB Cable
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.
Revision 3 of the board has the following new features:
- 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
- Stronger RESET circuit.
- Atmega 16U2 replace the 8U2.

Installing drivers for the Arduino Uno with Windows7, Vista, or XP:
1. 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
2. Click on the Start Menu, and open up the Control Panel.
3. While in the Control Panel, navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.
4. Look under Other devices. You should see an open port named "Arduino UNO"
5. Right click on the "Arduino UNO" and choose the "Update Driver Software" option.
6. Next, choose the "Browse my computer for Driver software" option.
7. Finally, navigate to locate the "Drivers" folder (NOT the "FTDI USB Drivers" sub-directory) under the Arduino IDE folder "Arduino-1.0.x".
8. A diaglog box with warning will pop out, select "Install this driver software anyway".
9. Windows will finish up the driver installation from there.
