Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

Installing drivers for the Arduino Uno 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 Other devices. You should see an open port named "Arduino UNO"
- Right click on the "Arduino UNO" and choose the "Update Driver Software" option.
- Next, choose the "Browse my computer for Driver software" option.
- Finally, navigate to locate the "Drivers" folder (NOT the "FTDI USB Drivers" sub-directory) under the Arduino IDE folder "Arduino-1.0.x".
- A diaglog box with warning will pop out, select "Install this driver software anyway".
- Windows will finish up the driver installation from there.
